To achieve a 100% conversion to silver metal a constant temperature of 85 to 95 C must be maintained during the whole process. Place the beaker in a water bath, together with a thermometer. Add NaOH in small doses while stirring vigorously. A very exothermic reaction occurs, but it'll not be enough to maintain the optimal temperature during the whole process, therefore a gentle heating underneath the water bath is necessary to keep the temperature correct for the remaining part of this process. I always place the beaker in a clamp on a metal lab stand in such a way it's hanging a bit above the bottom of the water bath, allowing the water to flow free under and around the beaker; thus avoiding any spots becoming too hot. The water helps dispersing the heat when the NaOH and especially later when the sugar is added; important to avoid caramelization of some sugar types. Adding NaOH as a near saturated aqueous solution calms down the violent reaction quite a lot, and keeping a constant temperature of 85 to 95 C, as well as later adding sugar dissolved in water, all reduces the total reaction time of this process. Beware of the delayed reaction when adding the sugar. After the first dose of sugar solution, stir and wait until it start reacting, then continue to stir and add more in small doses to avoid overflow/boil over. Both while adding NaOH, and later while adding sugar, temperature increases will occur so the external heat source must be adjusted accordingly.
You're an awesome man,showing exactly the production and answering questions too. This is why I love your videos. Thank you for your help and support for all who didn't pay attention in science class.
Great video. I am looking at alternative ways of recovering silver plate other than nitric. This silver chloride process is just what I was looking for. Would of loved to have seen the melt and weighing of bars. Can you do an updated video on the procedure now that you talk in your presentations. It's so much better that way because I don't have to be distracted while something is going on.
+charles connor - I dumped about 1/2 cup of sugar into the black silver oxide one time. At first it started to make some boiling noises, then it erupted and spewed hot caustic liquid and silver about a foot into the air. It was like a valcano! Add that sugar SLOWLY and stir.
You can use many different reducing agents in the last reaction. But, sucrose is cheap, even though it's only the glucose moiety of the disaccaride that is oxidised by silver oxide in lye. A very similar reaction is used for the semi quantity measurement of aldose sugars, by alkaline reduction of Cu²+ to Cu+", which is presipitated as Cu²O, as a redsish powder. The same reaction, using Ag+ as the nitrate, is used to make silver mirror. (E.g inside a sylinder or a scrying pool). The use of silver in magical procedures, are many! The most known, historically, is the manufacture of coins for circulation as money!
Have you looked into methods that recover silver directly from silver nitrate? I saw an interesting reaction in the silver nitrate entry in Wikipedia. Silver nitrate powder is heated above its melting point (250 degC) and begins to decompose. The decomposition is complete a higher temperatures (440 degC): 2 AgNO3 -> 2 Ag + O2 + 2 NO2 . This must be done in a well ventilated area, a fume hood preferably, because the nitrogen dioxide is toxic. Note that dry AgNO3 is used, so if you have it in solution form, you have to dry it first.
I've never done that. I alway dissolve the agno3 is distilled water, add a few drops of nitric and add some pieces of copper. The pure silver powder will cement out nicely on the copper. Then it can be collected in a filter and melted into a button or a bar then added to the electrolytic silver cell to make five nines fine pure silver crystal.
Check out the reactivity series of metals. Any metal that is more reactive will "cement" (reduce) any other metal that is less reactive located lower in the list. For example, iron will reduce copper out of a copper nitrate solution because iron is more reactive than copper. I use pieces of angle iron to treat my waste.
Sir I am very happy gram your information making gold and silver process But I want to know the information of mercury , from which could be make the gold , silver by mercury
I have very lil silver chloride to work with but wanted to see if I could convert it oxide but I'm only left with a dark grey substance. Did I not use enough sodium hydroxide? I used approximately an oz or two. Maybe lil more.... Then it went black and hot so I thought that was a signal to add sugar. And other then heat I'm getting no bubbles or reaction other then heat. Hmmm?
Ok so process done purple ceramic CPUs and I was told there is silver in waste in the form of silver chloride. And to get that I'd need to add HCL to my waste nitric and water. I did that and now it's milky. What's the next step? Do I try and clean solution some how?
Hey i figured an easier way of turning silver cloride into metal by adding alluminuim with a bit of hydrochloric acid enough to make it bubble and walla silver no lye no sugar no stirring just turns into silver the alluminuim goes into solution while precepting the silver maybe that help you out man cause i know thats a pain that stirring and cost man silver down to 20 dollars an ounce and how much sugar and lye we use it dont even out an ounce and time and you dont have to clean it it wont drop the copper just the silver i mean you can use zinc but zinc will drop everyhing in the book down and maybe when you got the metal if you use a lil soda and sugar it purify but just a lil tho not bags to turn it then it leave a copper solution with alluminuim if your a scraper thats the best news for you precept copper and alluminuim to take to scrap yard lol love you screetips
I have a mess on my hands. I have several pounds of silver. But I’m not sure what state it’s in and how to convert it to pure silver. It is waste from making mirrors. Silver nitrate/ sodium hydroxide/ammonia/glucose in deionized water. . It is a brown looking water. Where I have let settle to the bottom and dried the sludge it’s now in a dirt like form. Im needing help bad.
Great video as always, just a quick question. Does the purity of the sodium hydroxide have to be lab grade (99.9% pure) or can you use say 50% purity? The reason I ask is that the supplier I use has several types from 5% up to 70% pearls and 99.9% pure pellets. I wasn’t sure wether less purity basically meant you had to use more Lye or if it would affect the reaction with sugar? Thank you in anticipation of your reply. D.
Darren, I've never used anything less than the pure granuals that I buy from dudadiesel.com I get the 50 pound bucket of their red devil lye for $100 shipped. I think it's 99% pure. Lower purity lye may contain other impurities that could hurt the purity of the resulting silver.
We buy the Sterling silver at yard sales for pennies. Since this is more of a hobby than a business I rarely keep track of the amounts. Roughly, the material used to make the silver chloride cost about half of what I'll be able to sell it for. And yes, as long as all the lye and sugar is rinsed free, the silver powder will melt into 999 fine silver bars just like it is. But I always run it through the silver cell just to make sure.
I added sodium hydroxide, turning the color of silver chloride into brown, and then I added sugar, it turned gray, collected silver and rinsed it with water. After this, I added it to 100 grams and cast it, and the alloy became 80 grams. Is this natural deficiency, is there a problem?
Sound like you lost metal due to incomplete silver chloride to silver oxide reaction. I've he'd this happen when I first started. Experience will fix this. The more you do it the better you'll get at it. Today I use a hand held submersible blender to ensure complete conversion to silver oxide. My silver oxide looks black. Then I add the sugar.
Hi Sreetips. To get AgCl, can you just add HCl to your nitric base metal solution from the gold recovery and filter it out? Basically what I'm asking is how you convert AgNO3 to AgCl.
Yes. The only time distilled water is critical is when working with silver dissolved in nitric. If chlorinated tap water is added to silver nitrate solution then the silver will immediately react with the chlorine and form silver chloride. Silver chloride is very fine grained and will pass right through a filter paper. It's not easy to get it out of the solution once it gets in there.
Whats the best way to get the Silver out of spent A/R sludge.....? I have been saving the fluids or basicly HCL after I get the gold out of my Aqua Regia Solutions....I know theres silver in there....I put a copper pipe in it one time...A the copper pipe turned purple and zero silver came out of solution....next up on reactivity is lead...wich I have not tried....if I heat it up and add sodium hydroxide it will drop to the bottom as a black mud...then start over ..but there has got to be a easier way....Ha....From now on when I do my A/Rs and I filter and rinse the junk Ewaste off with Distilled Water..if I leave the nitric alone the silver automaticly drops to the bottom the next day...Then I will Denox with Urea and get my gold out with SMB.....Any ideas let me know....Could use any ideas....Thanks...
Seen a video of it that way..Feller had 12 Pentium Pro CPUs...Crushed them up then used a 50/50 water/nitric solution...Then processed the cpu's with A/R...His yield was a Gram loss of Au...When I wash and filter my A/R ..with distilled water...I just leave it sit afterwards and the silver chloride drops to the bottom the next day...Then I get the Nitric out to drop the gold....But I have 4 buckets of Too Late Smart with Silver in it.......:)
If you have silver chloride then you can clean with tap water. Put the AgCl in a container and add tap water and let it settle. Then siphone off the tap water and repeat until the silver chloride is clean. Then you can use lye and sugar to convert it to silver metal. I also know that silver chloride will dissolve in hot ammonia. Once dissolved in ammonia, the solids can be filtered out. Then HCl is added to the filtered solution to reform the silver chloride as a nice clean white powder. Then it can be converted to silver metal using lye and sugar.
hi sir can you please help me Whene i add sodium hydroxide (flakes ) to silver chloride it's turning orange\brown it's normal ? should i juste need to keep on stirring and add sodium hydroxide and sugar thank you
I keep adding sodium hydroxide until it turns completely black and no more white specs of silver chloride are visible. It takes lots of stirring. That's why I used a stirrer powered by my electric drill. Once it's black, then I add the sugar to convert the black silver oxide to grey metallic silver powder. That is how I do my silver chloride conversion.
Hi streetips ! I'm new on your chanel,, and i apreciate a lot your knowledge. When I have see this methode, a question come to me : Is it possible to transform aluminium metal in aluminium powder by disolving it in HCl, make Al2O3 by add to the AlCl3 some NaOH, and finaly convert the Al2O3 to Aluminium powder with the add of sugar? Thank a lot for your answer
@@sreetips thank for the fast answer. I'll subscribe to your chanel, you are doing a great work !! very clean and pedagogic I will do some more research about aluminium. good continuation
You add the sugar after it cools down....? Or add the sugar as soon as you stop seeing white specks . And it's still hot........? Or does it even matter.....?
I add the sugar immediately after all the white specks (silver chloride) turns to black (silver oxide). Some say that all the white specs need not be gone before you can add the sugar. But I've added sugar before all the white spec had converted to black silver oxide, and in the end there was white silver chloride mixed in with my grey silver powder. The white silver chloride does not turn to black silver oxide very easily. You can stir until the cows come home and still have unconverted white specs of silver chloride. That is the reason I made the stir bar with the model airplane propellers. It does a good job of converting 100% of the white silver chloride to black silver oxide. Based on my experience, it is better to completely convert the white silver chloride to black silver oxide before the sugar is added.
Ok ..So as soon as there is No more Chloride Spec's...Also probbly because they are Chunks that need broken apart....But when it is Still Heating Up...Add the Sugar...Ok Thanks Partner...i messed up...i waited to long ..When i added sugar it had stopped workin/heating...Haha...Mad Scientist Huh...? How we learn.......:) i can do gold real well...i need to work on Palladium...Think im just gona HCL the H.D. Disc's ..Then Melt whats left as Pt.....Thanks Rich......!
I don't think temperature matters. If you've converted all the silver chloride with lye to silver oxide then waiting for it to cool down should not hurt the reaction. You should be able to let it sit for several days, then add your sugar and the reaction will still happen even though it is cold. As soon as the sugar is added the whole batch will get hot real quick because the reaction s exothermic. I added sugar to a batch by just pouring in a whole cup all at once. It gurgled a little then erupted over the top of the 5 gallon bucket spilling hot silver, lye and sugar everywhere - like a volcano! I've learned from that experience to add the sugar slowly.
Haha....Mad Scienctist.....Me too....Yea my HAOH Reaction had stopped and Cooled...Then I added Sugar and No Exothermo Reaction...But I do have gray stuff at the bottom and the rest is black....Ha ...Next time I think...Besides I may try to Reheat...it took me quite a while to learn gold...guess im a hard head....Ha...Silver will probably be easy...I used to throw my silver chloride away...thought it was junk at the bottom of my A.R.s.....it was dropping out I guess because it can't stay in HNO3 ...And I would Rinse all the Ewaste with Distilled water...So I was really activating it ...Really tough to get all your Auric Acid out of Silver Chloride when it is at the bottom...And adding water or hcl would just put it back into solution....Ahhhh.....! Haha....Maybe if i Rinse with a Special Salt like Chlorate or something the S.Chloride would not dilute back into my Auric Gold Acid...i do know that gold was worth more than Darn Silver...But i will pay more attention ...Many Thanks Partner.....Rich...:)
Does being silver chloride convert it to silver metal? I find that it will melt, but I can't find anywhere what it melts into. I've looked through the grf. I have silver chloride but just a little. Messed up on my calculations on inquartation and added too much silver. It showed no more reactions to nitric, but because I had such fine particles of gold I foolishly didn't rinse it well enough. 2 days later of diluting and decanting I've almost got this silver chloride seperated, but I want to avoid the lye/sugar method if possible
Harold_V has melted silver chloride into silver metal by adding lots of sodium carbonate (not sodium bicarbonate). I’ve tried it but it’s not very efficient. I used to add to much silver or have a piece of non-gold metal get counted as karat gold and have the gold crumble to a powder. Makes separating the liquid from the gold difficult. When it happens I get the gold into a filter and put in a melt dish. Melt into a button, stir with a graphite rod to get a consistent alloy. Then test the button with acid to determine karat of the button. Then start all over and re-inquart. Some of the gold goes right through the filter because it’s in such a finely divided state. That’s why I end up using less silver rather than more to inquart. The book calls for a 25% gold alloy. But it can be as high as 30% or a little more and the nitric can still penetrate and yield a good result. But it may take extra nitric boils to get it all out. Good luck.
@@sreetips thank you. I think I'm going to do that and I guess I will just process some silver with the lye/ sugar method and quit trying to avoid it lol. I've also noticed the hotter it is outside, the more finely divided my gold drop with smb is! I'm thinking to set up an ice water bath for the next drop. Thank you for all your helpful info!
Hello again, I watch one of your previous video that you convert the silver into 9999.9 pure crystal with Copper. What's the best way, after you obtain AgNO3, using copper, which looks messy, or adding NaCl to obtain AgCl and then this video methode?
There's a debate amount silver refiners. Some like to extract Pd with DMG (you get your palladium up front) and then drop the silver chloride with salt. I prefer cementing the silver. Silver is a carrier of other precious metals, especially palladium because it too is soluble in nitric acid. If salt, lye, and sugar are used to get the pure silver from the AgNO3 then the PGMs get left behind in the rinse water. Using copper to cement will get the silver and the PGMs out of the AgNO3. The PGMs, if present, will cement out after the silver, as a fine black powder on the copper. Then the cement silver and the PGMs can be melted into shot and run through the silver cell. The PGMs should stay in the anode filter of the silver cell if the pH isn't too low in the electrolyte. Then the PGMs can be recovered and refined from those used silver cell filters. That's the way I like to do it.
Is this an experiment you could duplicate? Or Do you have an amount of HCL to to test so that that could be determined. Also you stated "moist," why was that?
My mistake, it was 2 liters of white silver chloride, not HCl (HCl is hydrochloric acid). If the silver chloride is allowed to dry out then the reaction with the sodium hydroxide to form silver oxide does not work very well. Keeping the silver chloride in a little water will keep it moist and promote the reaction for total conversion to the black silver oxide.
I made the AgCl buy adding hydrochloric acid to a silver nitrate solution. I made the silver nitrate solution by dissolving sterling/925 silver in dilute 50/50 distilled water and nitric acid. My wife bought the sterling silver at yards sales, and the thrift store.
hello i love your video but i have silver chloride as a precipitate , how do i recovery silver from a precipitate ? in other words does it have to be in solution first and how ?
First, don't let it dry out. Keep it moist. I have videos on how to convert the silver chloride to pure silver metal by adding lye and sugar. Adding lye converts the white silver chloride to jet black silver oxide. Then sugar is added to convert the silver oxide to silver metal (powder).
If you think you might have small amounts of palladium or platinum in your silver, what would happen to these metals if you used this method of refining the silver? Thanks
Since I sometimes need silver nitrate instead of silver metal, would it be possible to dissolve silver oxide in nitric acid instead of reducing the silver oxide with sugar to silver and then dissolving it? It would save one step. I found one chemical formula but not sure how the reaction works in reality: Ag2O + 2 HNO3 -> 2 AgNO3 + H2O
I've never done it, but I've been told that the black silver oxide can be melted into pure silver. So yes, the silver oxide can be dissolved in nitric. But first the silver chloride must be rinsed free of copper or else it too will still be in there. It's a real pain trying to get all the copper out of the silver chloride.
@@sreetipsThanks. There is no copper in my process. Silver nitrate solution is treated with table salt solution to precipitate silver chloride (sodium nitrate is a byproduct that stays dissolved), then the silver chloride is washed several times with water (to remove any leftover nitric acid and impurities) and then oxidised with sodium hydroxide 9I use 50% solution). I tried the follow up reduction with dextrose - it works well but it is hard to tell when the reaction is complete. I found the filtrate from the silver powder is dark brown and keeps light brown even after several washing. I am suspicious this is the oxidised sugar which is hard to separate from all the silver. Sometimes the silver powder is very fine and hard to filter. These are just two problems I found with this method and unable to find a way around so far - maybe by calculating stoichiometry and using only as little hydroxide and sugar as needed. Today I made silver nitrate crystals from the silver made by this process, the crystals were brown, but became perfectly clear after just one recrystallization. Unfortunately, the brown impurity is somewhat concerning to me. Next time I will try to guess a correct amount of sugar needed. I think it can be calculated from molar mass of glucose and estimated silver oxide produced. One alternative method is to dissolve silver chloride in ammonia solution, then precipitate silver metal directly with strong reducing agent, such as sodium dithionite (sodium hydrosulfite, a historical bleaching agent). This works perfectly, but your method is way cheaper on reagents and safer to perform.
Hello, I've been watching your videos and decided to try the sterling silver to pure silver. I started off with 610 grams sterling and 1500 ml distilled water with 700 ml 70% nitric. I filtered the silver nitrate then added my copper with a air pump. When I checked it this morning i could see cemented silver but I also have a greenish "foam" also. What is the "foam" and what did I do wrong? Is there silver in the "foam?" Any help would be great!!!
You probably have excess free nitric in the blue colored silver nitrate solution. If excess free nitric is present then it will needlessly consume the copper that you added, and cause heat and brown fumes. Plus the cement silver will dissolve just as soon as it cements out, causing it to float instead of staying on the bottom of the container. To avoid this, when dissolving silver, I always add small amounts of nitric acid with heat, waiting for the reaction to die down before adding more small doses of nitric. Also, I make sure that there are pieces of silver that don't dissolve left over after all fumes cease and before cooling and filtering. This will ensure that all the nitric acid has been completely consumed.
@@sreetips Mr. Sreetips 1- I hope the video that you will make it done with good clarification and show values like this one. 2- Do you have an email to make it easy to contact you if there any inquiry?
It's amazing how you realize "ooops" whe. You have HCL & gold fingers in one beaker, and think "oh ill just add this to that beaker with Copper and silver nitrate and Viola! A milky mess!!! At least it was only 100ml sheesh. If I'd dumped it into my 1000ml containing 400g of silver I'd be pretty upset...
@@sreetips I own 100 grams of silver chloride, I put sodium hydroxide, and I turned it into silver oxide. I added sugar, but no violent reaction occurred like what I saw in this video.
@@sreetips But after adding the sugar, no violent reaction occurred, and the silver oxide did not convert into pure silver. What errors can he commit that lead to the failure of the process of sugar interaction with silver?
But... Where did you get the silver Nitrate? I want to know where you got the raw materials from to do this process, and how much profit you got at the end of it from selling it after you did the electrolysis to crystallise the pure silver out
+tiggerbiggo please look at my video entitled "Silver Refining Complete Process For The Amateur Refiner 1of2" in that video I make some impure silver shot for my electrolytic silver cell. It shows how I process the raw sterling silver by dissolving it in nitric acid. After dissolving I filter out the solids and the add copper to cement out the silver from the filtered silver nitrate solution. Instead of cementing, like I did in that video, I simply added hydrochloric acid to instantly form silver chloride. I bought the raw silver from yard sales, thrift stores, consignment shops, estate sales, and private individuals. The cost of the raw silver was about 10 cents ($0.10) per gram. After processing I can get about $0.54 per gram for the pure silver crystal with spit silver at around $15.50 per Troy ounce. Hope this helps
The copper nitrate is placed in a bucket full of iron. The copper cements out and the iron goes into solution. The copper is then then just thrown away. Nobody wants it because it has other metals in with it. I can't even give it away.
silver nitrate should dissolve in hot DISTILLED water. Don't use tap water, it will cause the solution to become cloudy because the silver nitrate will react with the dissolved chlorides in the tap water and form silver chloride.
Cyrus, I've never measured. I can tell when enough sodium hydroxide is in when the snow-white silver chloride has turned pitch black. But I seem to remember that is took about 2 pounds (just under a kilo) of NaOH with my 4 liter beaker 40% full of moist silver chloride sitting in water. Don't let the chloride dry out, keep it moist at all times. Dried out silver chloride that's been rehydrated doesn't react as well for some reason.
I've never done it so I don't know. But I'm told that the silver oxide can be melted into pure silver without the sugar. Washing the NaOH from the silver oxide and melting it straight away would make an interesting video.
@@sreetips the research ive done said it may not be strong enough and dry lye is recommended plus it's cheap but liquid lye (drain cleaner)is what I have on hand. Maybe because you do some videos using house hold chemicals you can do a video on using drain cleaner instead of dry lye just a suggestion
AHMAD I’ve never taken the time to calculate how much lye or sugar to add. I just add lye until the snow-white silver chloride turns to jet-black silver oxide, then I add small amounts of sugar until the jet-black silver oxide turns to gray-colored pure elemental silver powder. I’ve never measured or calculated the stoichiometry. Just did the reaction by the seat of my pants.
+libertad para siempre - it is a cordless electric drill held by a lab clamp and ring stand. The purpose is to stir the silver chloride so I don't have to stir it manually.
+libertad para siempre - that was an infrared temperature gun with a laser pointer. I was using it to show the temperature of the reaction as it progressed. In the last frame I used it the reaction was quite hot at 234 degrees F.

Yes, it will be three nines fine if you get all the copper rinsed out before you do the conversion to silver oxide with the NaOH. Also, Make sure any excess NaOH is rinsed out before you dry and melt the pure silver powder. I use pH test strips until I get a pH test of 6.5 or so. I use tap water to rinse it out, tap water is slightly acidic in my area.
I've never bought silver chloride, I make it by adding hydrochloric acid to a silver nitrate solution. Then I rinse it over and over with tap water to get all the copper out. I test the rinse water with ammonia, it will turn blue if copper is still in the rinse. Then i do the lye and sugar reaction. To get 1 kilo of silver I would start with dissolving 1.2 kilos of Sterling silver in hot, dilute 50/50 nitric acid/distilled water. Sterling silver is about 90% pure silver, the rest is copper.
Hello, I've never used metal to stir the silver chloride. I've only used PVC (poly vinyl chloride), and model airplane propellers with a threaded bolt made of nylon.
Aluminum reacts with lye solution so don't use aluminum. A plastic propeller would be better. As I said before. I've never used wood or metal so I have no experience to share with you on this.
I know silver nitrate is made by dissolving pure silver metal in nitric acid. Sulfuric acid will dissolve silver but it doesn't do it very well. I think silver sulfate is pure silver metal dissolved in sulfuric acid. But I'm not a chemist and thats only a guess!
I had refine silver chloride with lye and sugar. After getting powder I melted it. After melting there is no rigidity in melted crystal and when I beat the crystal it spreads like a stone. What should I do?
To achieve a 100% conversion to silver metal a constant temperature of 85 to 95 C must be maintained during the whole process.
Place the beaker in a water bath, together with a thermometer. Add NaOH in small doses while stirring vigorously. A very exothermic reaction occurs, but it'll not be enough to maintain the optimal temperature during the whole process, therefore a gentle heating underneath the water bath is necessary to keep the temperature correct for the remaining part of this process.
I always place the beaker in a clamp on a metal lab stand in such a way it's hanging a bit above the bottom of the water bath, allowing the water to flow free under and around the beaker; thus avoiding any spots becoming too hot. The water helps dispersing the heat when the NaOH and especially later when the sugar is added; important to avoid caramelization of some sugar types.
Adding NaOH as a near saturated aqueous solution calms down the violent reaction quite a lot, and keeping a constant temperature of 85 to 95 C, as well as later adding sugar dissolved in water, all reduces the total reaction time of this process.
Beware of the delayed reaction when adding the sugar. After the first dose of sugar solution, stir and wait until it start reacting, then continue to stir and add more in small doses to avoid overflow/boil over.
Both while adding NaOH, and later while adding sugar, temperature increases will occur so the external heat source must be adjusted accordingly.

Very clear and comprehensive explanation
Have you looked into methods that recover silver directly from silver nitrate? I saw an interesting reaction in the silver nitrate entry in Wikipedia. Silver nitrate powder is heated above its melting point (250 degC) and begins to decompose. The decomposition is complete a higher temperatures (440 degC): 2 AgNO3 -> 2 Ag + O2 + 2 NO2 . This must be done in a well ventilated area, a fume hood preferably, because the nitrogen dioxide is toxic. Note that dry AgNO3 is used, so if you have it in solution form, you have to dry it first.
I've never done that. I alway dissolve the agno3 is distilled water, add a few drops of nitric and add some pieces of copper. The pure silver powder will cement out nicely on the copper. Then it can be collected in a filter and melted into a button or a bar then added to the electrolytic silver cell to make five nines fine pure silver crystal.
That sounds good, too. I didn't know that Cu reduces Ag^+1.
Check out the reactivity series of metals. Any metal that is more reactive will "cement" (reduce) any other metal that is less reactive located lower in the list. For example, iron will reduce copper out of a copper nitrate solution because iron is more reactive than copper. I use pieces of angle iron to treat my waste.

Next, why did you remove the propellers? Seems a bit premature not to use the best stirrers you had
I wonder if this would work with other chlorides ?
Just thinking out loud.
I try puting salt into the silver aqua regia an it didn't turn white like it supposed to I going try suger an lye method
Hey i figured an easier way of turning silver cloride into metal by adding alluminuim with a bit of hydrochloric acid enough to make it bubble and walla silver no lye no sugar no stirring just turns into silver the alluminuim goes into solution while precepting the silver maybe that help you out man cause i know thats a pain that stirring and cost man silver down to 20 dollars an ounce and how much sugar and lye we use it dont even out an ounce and time and you dont have to clean it it wont drop the copper just the silver i mean you can use zinc but zinc will drop everyhing in the book down and maybe when you got the metal if you use a lil soda and sugar it purify but just a lil tho not bags to turn it then it leave a copper solution with alluminuim if your a scraper thats the best news for you precept copper and alluminuim to take to scrap yard lol love you screetips
Thanks, appreciate the tip.
I have a mess on my hands. I have several pounds of silver. But I’m not sure what state it’s in and how to convert it to pure silver. It is waste from making mirrors. Silver nitrate/ sodium hydroxide/ammonia/glucose in deionized water. . It is a brown looking water. Where I have let settle to the bottom and dried the sludge it’s now in a dirt like form. Im needing help bad.
All those together is a little beyond my experience level.
sreetips I’ve spent weeks trying to research.
Another really good video. Thanks.
Great video as always, just a quick question. Does the purity of the sodium hydroxide have to be lab grade (99.9% pure) or can you use say 50% purity? The reason I ask is that the supplier I use has several types from 5% up to 70% pearls and 99.9% pure pellets. I wasn’t sure wether less purity basically meant you had to use more Lye or if it would affect the reaction with sugar? Thank you in anticipation of your reply. D.
Darren, I've never used anything less than the pure granuals that I buy from dudadiesel.com I get the 50 pound bucket of their red devil lye for $100 shipped. I think it's 99% pure. Lower purity lye may contain other impurities that could hurt the purity of the resulting silver.
50% is fine. I test caustic soda samples for Brenntag and Univar. The only contaminants are iron (1 ppm) sodium carbonate (
Excellent video and thanks for posting.

How much AgNO3 to make 2 liter of AgCl ?
I’ve never taken the time to calculate it. Sorry
This has got to be the most ghetto refining process I have ever seen.
I fucking love it!
can you then re-melt the silver powder into bars? also...what is the cost of the silver chloride to begin with....roughly? nice video . thanks!
We buy the Sterling silver at yard sales for pennies. Since this is more of a hobby than a business I rarely keep track of the amounts. Roughly, the material used to make the silver chloride cost about half of what I'll be able to sell it for. And yes, as long as all the lye and sugar is rinsed free, the silver powder will melt into 999 fine silver bars just like it is. But I always run it through the silver cell just to make sure.
Can you please do the same process only with iron powder ?
Iron is a very dirty metal.
I added sodium hydroxide, turning the color of silver chloride into brown, and then I added sugar, it turned gray, collected silver and rinsed it with water. After this, I added it to 100 grams and cast it, and the alloy became 80 grams. Is this natural deficiency, is there a problem?
Sound like you lost metal due to incomplete silver chloride to silver oxide reaction. I've he'd this happen when I first started. Experience will fix this. The more you do it the better you'll get at it. Today I use a hand held submersible blender to ensure complete conversion to silver oxide. My silver oxide looks black. Then I add the sugar.
@@sreetips
Is silver supposed after adding sugar to not decrease something from it after casting?
@@sreetips
Please can you send me your Facebook to contact with you?
Hi Sreetips. To get AgCl, can you just add HCl to your nitric base metal solution from the gold recovery and filter it out? Basically what I'm asking is how you convert AgNO3 to AgCl.
That's one way, HCl to silver nitrate will make silver chloride. Saturated sodium chloride (table salt) solution will also make the silver chloride.
@@sreetips Thanks a ton. Good thing I've been saving that solution. Once I have a good bit, I'll be working on that.
Another good one from you.
Hi.
Do you mean that you used 2L silver chloride and got 2.5-3 kg silver powder??
Those amounts were guesstimates. If I remember there was a little less that 2 kilos after I melted it.
Nice job Sr., I want to know if you can use raw water to pour silver liquid metal to make silver shot or it it is necessary to use distilled water
Thanks for your support!!!
I use chlorinated tap water when pouring the molten silver into shot
@@sreetips So, ice could be made from chlorinated tap water, right??
Yes. The only time distilled water is critical is when working with silver dissolved in nitric. If chlorinated tap water is added to silver nitrate solution then the silver will immediately react with the chlorine and form silver chloride. Silver chloride is very fine grained and will pass right through a filter paper. It's not easy to get it out of the solution once it gets in there.
It seems like no matter how much rinsing my cement silver converted from silver chloride lye sugar method, rinse water stays muddy brown?
I know the feeling
Whats the best way to get the Silver out of spent A/R sludge.....? I have been saving the fluids or basicly HCL after I get the gold out of my Aqua Regia Solutions....I know theres silver in there....I put a copper pipe in it one time...A the copper pipe turned purple and zero silver came out of solution....next up on reactivity is lead...wich I have not tried....if I heat it up and add sodium hydroxide it will drop to the bottom as a black mud...then start over ..but there has got to be a easier way....Ha....From now on when I do my A/Rs and I filter and rinse the junk Ewaste off with Distilled Water..if I leave the nitric alone the silver automaticly drops to the bottom the next day...Then I will Denox with Urea and get my gold out with SMB.....Any ideas let me know....Could use any ideas....Thanks...
I don't have any experience with what you are referring to. It is best to remove the silver with dilute nitric acid before you go to AR.
Seen a video of it that way..Feller had 12 Pentium Pro CPUs...Crushed them up then used a 50/50 water/nitric solution...Then processed the cpu's with A/R...His yield was a Gram loss of Au...When I wash and filter my A/R ..with distilled water...I just leave it sit afterwards and the silver chloride drops to the bottom the next day...Then I get the Nitric out to drop the gold....But I have 4 buckets of Too Late Smart with Silver in it.......:)
If you have silver chloride then you can clean with tap water. Put the AgCl in a container and add tap water and let it settle. Then siphone off the tap water and repeat until the silver chloride is clean. Then you can use lye and sugar to convert it to silver metal. I also know that silver chloride will dissolve in hot ammonia. Once dissolved in ammonia, the solids can be filtered out. Then HCl is added to the filtered solution to reform the silver chloride as a nice clean white powder. Then it can be converted to silver metal using lye and sugar.
hi sir can you please help me
Whene i add sodium hydroxide (flakes ) to silver chloride it's turning orange\brown it's normal ? should i juste need to keep on stirring and add sodium hydroxide and sugar
thank you
I keep adding sodium hydroxide until it turns completely black and no more white specs of silver chloride are visible. It takes lots of stirring. That's why I used a stirrer powered by my electric drill. Once it's black, then I add the sugar to convert the black silver oxide to grey metallic silver powder. That is how I do my silver chloride conversion.
Hi streetips ! I'm new on your chanel,, and i apreciate a lot your knowledge.
When I have see this methode, a question come to me :
Is it possible to transform aluminium metal in aluminium powder by disolving it in HCl, make Al2O3 by add to the AlCl3 some NaOH, and finaly convert the Al2O3 to Aluminium powder with the add of sugar?
Thank a lot for your answer
I've never worked with alumininum so I don't know.
@@sreetips thank for the fast answer. I'll subscribe to your chanel, you are doing a great work !! very clean and pedagogic
I will do some more research about aluminium.
good continuation
You add the sugar after it cools down....? Or add the sugar as soon as you stop seeing white specks . And it's still hot........? Or does it even matter.....?
I add the sugar immediately after all the white specks (silver chloride) turns to black (silver oxide). Some say that all the white specs need not be gone before you can add the sugar. But I've added sugar before all the white spec had converted to black silver oxide, and in the end there was white silver chloride mixed in with my grey silver powder. The white silver chloride does not turn to black silver oxide very easily. You can stir until the cows come home and still have unconverted white specs of silver chloride. That is the reason I made the stir bar with the model airplane propellers. It does a good job of converting 100% of the white silver chloride to black silver oxide. Based on my experience, it is better to completely convert the white silver chloride to black silver oxide before the sugar is added.
Ok ..So as soon as there is No more Chloride Spec's...Also probbly because they are Chunks that need broken apart....But when it is Still Heating Up...Add the Sugar...Ok Thanks Partner...i messed up...i waited to long ..When i added sugar it had stopped workin/heating...Haha...Mad Scientist Huh...? How we learn.......:) i can do gold real well...i need to work on Palladium...Think im just gona HCL the H.D. Disc's ..Then Melt whats left as Pt.....Thanks Rich......!
I don't think temperature matters. If you've converted all the silver chloride with lye to silver oxide then waiting for it to cool down should not hurt the reaction. You should be able to let it sit for several days, then add your sugar and the reaction will still happen even though it is cold. As soon as the sugar is added the whole batch will get hot real quick because the reaction s exothermic. I added sugar to a batch by just pouring in a whole cup all at once. It gurgled a little then erupted over the top of the 5 gallon bucket spilling hot silver, lye and sugar everywhere - like a volcano! I've learned from that experience to add the sugar slowly.
Haha....Mad Scienctist.....Me too....Yea my HAOH Reaction had stopped and Cooled...Then I added Sugar and No Exothermo Reaction...But I do have gray stuff at the bottom and the rest is black....Ha ...Next time I think...Besides I may try to Reheat...it took me quite a while to learn gold...guess im a hard head....Ha...Silver will probably be easy...I used to throw my silver chloride away...thought it was junk at the bottom of my A.R.s.....it was dropping out I guess because it can't stay in HNO3 ...And I would Rinse all the Ewaste with Distilled water...So I was really activating it ...Really tough to get all your Auric Acid out of Silver Chloride when it is at the bottom...And adding water or hcl would just put it back into solution....Ahhhh.....! Haha....Maybe if i Rinse with a Special Salt like Chlorate or something the S.Chloride would not dilute back into my Auric Gold Acid...i do know that gold was worth more than Darn Silver...But i will pay more attention ...Many Thanks Partner.....Rich...:)
Does being silver chloride convert it to silver metal? I find that it will melt, but I can't find anywhere what it melts into. I've looked through the grf.
I have silver chloride but just a little. Messed up on my calculations on inquartation and added too much silver. It showed no more reactions to nitric, but because I had such fine particles of gold I foolishly didn't rinse it well enough.
2 days later of diluting and decanting I've almost got this silver chloride seperated, but I want to avoid the lye/sugar method if possible
Harold_V has melted silver chloride into silver metal by adding lots of sodium carbonate (not sodium bicarbonate). I’ve tried it but it’s not very efficient. I used to add to much silver or have a piece of non-gold metal get counted as karat gold and have the gold crumble to a powder. Makes separating the liquid from the gold difficult. When it happens I get the gold into a filter and put in a melt dish. Melt into a button, stir with a graphite rod to get a consistent alloy. Then test the button with acid to determine karat of the button. Then start all over and re-inquart. Some of the gold goes right through the filter because it’s in such a finely divided state. That’s why I end up using less silver rather than more to inquart. The book calls for a 25% gold alloy. But it can be as high as 30% or a little more and the nitric can still penetrate and yield a good result. But it may take extra nitric boils to get it all out. Good luck.
@@sreetips thank you. I think I'm going to do that and I guess I will just process some silver with the lye/ sugar method and quit trying to avoid it lol.
I've also noticed the hotter it is outside, the more finely divided my gold drop with smb is! I'm thinking to set up an ice water bath for the next drop.
Thank you for all your helpful info!
Hello again, I watch one of your previous video that you convert the silver into 9999.9 pure crystal with Copper. What's the best way, after you obtain AgNO3, using copper, which looks messy, or adding NaCl to obtain AgCl and then this video methode?
There's a debate amount silver refiners. Some like to extract Pd with DMG (you get your palladium up front) and then drop the silver chloride with salt. I prefer cementing the silver. Silver is a carrier of other precious metals, especially palladium because it too is soluble in nitric acid. If salt, lye, and sugar are used to get the pure silver from the AgNO3 then the PGMs get left behind in the rinse water. Using copper to cement will get the silver and the PGMs out of the AgNO3. The PGMs, if present, will cement out after the silver, as a fine black powder on the copper. Then the cement silver and the PGMs can be melted into shot and run through the silver cell. The PGMs should stay in the anode filter of the silver cell if the pH isn't too low in the electrolyte. Then the PGMs can be recovered and refined from those used silver cell filters. That's the way I like to do it.
The last one, when I was adding sugar no cementation appeared. What is the fault.
That’s very strange.
you use "just under two liters" of HC. How much I'd that be weight?
Great job on the videos. l watch all the time.
Terry, I don't keep accurate records of the amounts I use. This is just a hobby for me. I don't know what the weight of the HCl is.
Is this an experiment you could duplicate? Or Do you have an amount of HCL to to test so that that could be determined.
Also you stated "moist," why was that?
My mistake, it was 2 liters of white silver chloride, not HCl (HCl is hydrochloric acid). If the silver chloride is allowed to dry out then the reaction with the sodium hydroxide to form silver oxide does not work very well. Keeping the silver chloride in a little water will keep it moist and promote the reaction for total conversion to the black silver oxide.
Where dose one purchase, or aquire, AgCl in such quantities to use in my future hobbies?
I made the AgCl buy adding hydrochloric acid to a silver nitrate solution. I made the silver nitrate solution by dissolving sterling/925 silver in dilute 50/50 distilled water and nitric acid. My wife bought the sterling silver at yards sales, and the thrift store.
how much silver chloride you have taken
Sreetips, when you put the sugar into the solution, how do you know that you are completely done with the sugar?
The bubbling stops. That's when I know enough sugar has been added.
How much water did you mix, and what amount of AgCl did you put in it? Or did you buy it liquid?
I didn’t measure the amount of water. I put in the amount of silver chloride that I had on hand. I’ve never bought the liquid
hello i love your video but i have silver chloride as a precipitate , how do i recovery silver from a precipitate ? in other words does it have to be in solution first and how ?
First, don't let it dry out. Keep it moist. I have videos on how to convert the silver chloride to pure silver metal by adding lye and sugar. Adding lye converts the white silver chloride to jet black silver oxide. Then sugar is added to convert the silver oxide to silver metal (powder).
Lye should be mesured or not? What is the role of sugar here?
Sugar provides carbon - not sure how that works
Can I use iron to silver chloride instead of lye and sugar
I’ve never tried iron to silver chloride.
If you think you might have small amounts of palladium or platinum in your silver, what would happen to these metals if you used this method of refining the silver? Thanks
After dropping the silver chloride the traces of Pt and Pd would be left in the solution. To get them you could add copper and cement them out.
Since I sometimes need silver nitrate instead of silver metal, would it be possible to dissolve silver oxide in nitric acid instead of reducing the silver oxide with sugar to silver and then dissolving it? It would save one step.
I found one chemical formula but not sure how the reaction works in reality:
Ag2O + 2 HNO3 -> 2 AgNO3 + H2O
I've never done it, but I've been told that the black silver oxide can be melted into pure silver. So yes, the silver oxide can be dissolved in nitric. But first the silver chloride must be rinsed free of copper or else it too will still be in there. It's a real pain trying to get all the copper out of the silver chloride.
@@sreetipsThanks. There is no copper in my process. Silver nitrate solution is treated with table salt solution to precipitate silver chloride (sodium nitrate is a byproduct that stays dissolved), then the silver chloride is washed several times with water (to remove any leftover nitric acid and impurities) and then oxidised with sodium hydroxide 9I use 50% solution). I tried the follow up reduction with dextrose - it works well but it is hard to tell when the reaction is complete. I found the filtrate from the silver powder is dark brown and keeps light brown even after several washing. I am suspicious this is the oxidised sugar which is hard to separate from all the silver. Sometimes the silver powder is very fine and hard to filter. These are just two problems I found with this method and unable to find a way around so far - maybe by calculating stoichiometry and using only as little hydroxide and sugar as needed.
Today I made silver nitrate crystals from the silver made by this process, the crystals were brown, but became perfectly clear after just one recrystallization. Unfortunately, the brown impurity is somewhat concerning to me. Next time I will try to guess a correct amount of sugar needed. I think it can be calculated from molar mass of glucose and estimated silver oxide produced.
One alternative method is to dissolve silver chloride in ammonia solution, then precipitate silver metal directly with strong reducing agent, such as sodium dithionite (sodium hydrosulfite, a historical bleaching agent). This works perfectly, but your method is way cheaper on reagents and safer to perform.
Hello,
I've been watching your videos and decided to try the sterling silver to pure silver. I started off with 610 grams sterling and 1500 ml distilled water with 700 ml 70% nitric. I filtered the silver nitrate then added my copper with a air pump. When I checked it this morning i could see cemented silver but I also have a greenish "foam" also. What is the "foam" and what did I do wrong? Is there silver in the "foam?" Any help would be great!!!
You probably have excess free nitric in the blue colored silver nitrate solution. If excess free nitric is present then it will needlessly consume the copper that you added, and cause heat and brown fumes. Plus the cement silver will dissolve just as soon as it cements out, causing it to float instead of staying on the bottom of the container. To avoid this, when dissolving silver, I always add small amounts of nitric acid with heat, waiting for the reaction to die down before adding more small doses of nitric. Also, I make sure that there are pieces of silver that don't dissolve left over after all fumes cease and before cooling and filtering. This will ensure that all the nitric acid has been completely consumed.
sreetips Thank you. What can I do to salvage the mess? I don't want to lose the silver!

+tiggerbiggo No, I added hydrochloric acid to silver nitrate to make the silver chloride.
But... Where did you get the silver Nitrate? I want to know where you got the raw materials from to do this process, and how much profit you got at the end of it from selling it after you did the electrolysis to crystallise the pure silver out
+tiggerbiggo please look at my video entitled "Silver Refining Complete Process For The Amateur Refiner 1of2" in that video I make some impure silver shot for my electrolytic silver cell. It shows how I process the raw sterling silver by dissolving it in nitric acid. After dissolving I filter out the solids and the add copper to cement out the silver from the filtered silver nitrate solution. Instead of cementing, like I did in that video, I simply added hydrochloric acid to instantly form silver chloride. I bought the raw silver from yard sales, thrift stores, consignment shops, estate sales, and private individuals. The cost of the raw silver was about 10 cents ($0.10) per gram. After processing I can get about $0.54 per gram for the pure silver crystal with spit silver at around $15.50 per Troy ounce. Hope this helps

sir if silver nitrate is avaliable how can we dislove it pls let us know
silver nitrate should dissolve in hot DISTILLED water. Don't use tap water, it will cause the solution to become cloudy because the silver nitrate will react with the dissolved chlorides in the tap water and form silver chloride.
how much NaOH and dexrose we have to mix for 1 kg of silver chloride ?
Cyrus, I've never measured. I can tell when enough sodium hydroxide is in when the snow-white silver chloride has turned pitch black. But I seem to remember that is took about 2 pounds (just under a kilo) of NaOH with my 4 liter beaker 40% full of moist silver chloride sitting in water. Don't let the chloride dry out, keep it moist at all times. Dried out silver chloride that's been rehydrated doesn't react as well for some reason.

I’ve never measured or calculated the stoichiometry. Just did the reaction by the seat of my pants.

wait this is other way to make silver powder??
Yes, it will be three nines fine if you get all the copper rinsed out before you do the conversion to silver oxide with the NaOH. Also, Make sure any excess NaOH is rinsed out before you dry and melt the pure silver powder. I use pH test strips until I get a pH test of 6.5 or so. I use tap water to rinse it out, tap water is slightly acidic in my area.
soo i have to go buy Silver Chloride? i want at less 1 kilo of silver powder i need it for my project.. how much Silver Chloride i need?
and would this step work for gold chloride?
I've never bought silver chloride, I make it by adding hydrochloric acid to a silver nitrate solution. Then I rinse it over and over with tap water to get all the copper out. I test the rinse water with ammonia, it will turn blue if copper is still in the rinse. Then i do the lye and sugar reaction. To get 1 kilo of silver I would start with dissolving 1.2 kilos of Sterling silver in hot, dilute 50/50 nitric acid/distilled water. Sterling silver is about 90% pure silver, the rest is copper.
No, gold can't be done the same way.
