Bro, I gotta give you props. You just spent a ton of time recovering less than a third of an ounce of gold because it would have been a waste of money to let it go, but you didn't break the 40 minute video down into parts to capitalize on the TH-cam revenue. Because you know we would have all watched 2-4 videos of this as a series. Good man.
I am watching a silver refining for the first time right now and I have been stuck on the 2nd of however many because for 5 days now, I keep passing out. I am cool with that. This is the channel I put on whenever I put the kids to bed andit is my time to relax or go to sleep.
You truly spoil us! I remember the last one, thinking that you save them up for so long that it would be a really long time until we got to see an new filter paper recovery video again. Thanks!
These videos where you recover metals from dirty sources a careless refiner might throw away are some of my favorites. I love the more basic ones too of course, like the last one with the catches, they refresh the memory and it's always a treat to watch gold solutions get clearer and clearer and then watch that high purity gold powder coalesce. I don't thank you nearly often enough for all this cool work you're sharing with us. You should be commanded for carrying that heavy looking microphone contraption on your head for hours on end alone. I've been thinking that a Zoom F2 recorder (no clipping ever thanks to 32-bit float recording magic) with a proximity omnidirectional lavalier microphone like the AT803 could be the perfect audio set up for you. It's not exactly cheap, but it's amazing hardware. I believe that you like to sync up the audio and video in real time directly in your phone as you film in order to save time in the editing room though and that isn't possible (as far as I know) with the Zoom F2 unfortunately.
It’s funny how things or people can pass down their love for a certain thing…the videos of Sreetips, Nilered, BigstackD and Cody’s Lab made me learn a lot about chemistry, metals and all their reactions. Even though I don’t have the room or money to set up something like this, I do have a lot of books and cubed metals about this subject 😇 So thank you Sreetips for teaching us so much about this wonderful subject! Great video as always ☺️
Watching the cacophony of colors that came busting out of the pot when you stirred it was awesome. To think of all the different substances left behind on those filters. Another impressive video as always, thank you for your time to keep the videos a healthy length. I enjoy having them play on my second monitor. A certain ASMR value to the whole thing on top of the font of knowledge you offer us. Bravo.
I keep watching these videos and envisioning what I'm going to do in my retirement. Thank you so much for inspiring this in me. I can't understand what it is about how your videos make me watch 40 minutes without getting bored, but you've managed to do it. If you described what the video was about to me, and I hadn't seen one of your videos before, I'd give it a hard pass. But your approach to filming this stuff is educational and fascinating to watch. Thanks again!
Love it! I’m newer to the channel but it’s always relaxing to watch these videos and listening to the ambiance reminds me of a recovery of my health last year. = )
Love your videos, and how you explain everything so that even a novice can understand most of what's going on. To the point, informative and no extra "mumbo jumbo", makes it a comfortable and relaxing video to watch, and I can spend hours watching you extract metals rather than watching a movie or whatever. Big shout out from Norway! Keep those videos coming Sreetips! :D
@@sreetips I suggest that when you are filtering the results of your aqua region boil it would be better to avoid adding the solids in to the filter - repeatedly rinse the residues in the beaker until the solution runs clear. This is easier than rinsing and stirring the solids once they have been added to the filter funnel and you avoid the risk of ripping the paper.
I love these vids. You do such a fantastic job of narrating your videos. Your voice is buttery smooth ;). The yellow liquid oozing out of the solid looked like butter!
I love it. You give a lot of meaning to 4,9s fine. I still have my older hvac refrigerant recovery vacuum pump and gages which I use in my back yard refinery.
You’re welcome! It was my pleasure to watch this excellent production. Your investment in a proper vacuum pump system is a wise decision. Quite surprising is the length of time to draw the liquid through a filter that ends up looking like it’s nearly clean in the end. 👍👍🤟.
I think I’ve finally collected all the supplies needed to do my first refining….I’ve enquarted my 10-14k scrap that I’m using last night! Thanks for showing me the way sensei!
That's quite a collection of particles that didn't go through the screening process! Might be worth getting a coffee grinder to chop it up into little bits. They're super cheap. The coarse material will probably blunt the blades fairly quickly but they'd chop it all up into a finely divided state and any iron filings from the blades would be easily removable with a neodymium magnet.
Much thanks for all the recent great content. Was a huge help having stuff to watch in the hospital last week dealing with a foot surgery. Showed some of my nurses your stuff and they were really interested. Also showed to one of my doctors and that started a really cool conversation about chemistry and whatnot. Was this yield about what you expected from all the filters?
He can't seem to ever be able to resist putting the wood he cuts in his yard to good use burning some metal bearing material that needs incinerating. He did it the last time already when he cut down a tree. It's nice, might as well use carbon his yard extracted from the atmosphere than carbon fetched deep underground by energy companies. :)
Wonderful refining of those old collected material sir! Goes without saying this was pure hard work and knowledge. A bit of an extra insight about your personal experience between @19:10 - @19:30 is what we go through in this subject on a regular basis. I guess its like we never stop learning and every new discovery makes it even more fascinating and an enjoying procedure. Nonetheless it was another soothing video to watch since all your procedures are well demonstrated and explained. GREAT JOB! P.S Im still intrigued to learn how those specially prepared filter papers were actually prepared @12:50 and @20:55. Many Thanks!
Really nice recovery! I was wondering if it makes sense to save a bunch of these smaller recovery buttons after a single refining and then refine them all together to make a "three nines" gold bar. I can definitely see how a single refining of these buttons makes a lot of sense (from a time and materials perspective). Really nice video!
Thank you, everything! Your videos are so satisfying. I get my "fix" from yours specifically, coming down to your meticulous attention to detail. Please keep it up. You definitely hooked me with the 20k usd gold bar that one time
Some people may look at these yields and be disappointed but I see it as the filtering process you use works very well. Ideally there shouldn't be anything there to recover so the less there is the better you've done the earlier stuff. But it reminds of the last few batches I've done over the last 3 weeks. I did some filters and I did another stockpot cleaning. The filters had almost no gold and only a few grams of silver, and I was good with that. After I siphoned off the copper rich liquor from the stockpot and into one with an old brake rotor in it I let it sit until no more copper came out of solution (at least 3 months). I've been recovering the copper mostly out of personal interest and curiosity and I've made a small copper electro cell. With this last stockpot I melted all the slimes and copper together and poured it as an anode bar. When I ran that through the cell there was a surprising amount of black dust building up on the bottoms of the cell. It was super rich in gold and PGMs which told me that there could be a lot left in that bucket after the copper appears to stop working. Testing the first stage in the stockpot showed no precious metals in solution but they sure came out on the iron. The copper from the cell is just going to go back to cementing silver. When I incinerated the filters I was shocked with a very sudden flare up and flash. I'm guessing that there were some filters in there that I had used when I recovered the KNO3 from my nitrate solutions. They provided a nice hit of O2 at the wrong moment. Whole yard smelled like fireworks for an hour. :)
Another great video Dr. Sreetips! Many thanks for your easy to understand explanations! Also a great reminder to do my filter papers. How much silver did you get? Take Care, Jim in Phoenix
There was probably a couple ounces in there. But I didn’t recover it completely. I added some more silver nitrate from my gold extraction to keep my stream of silver recovery flowing. It’s a never ending battle to keep up with the silver.
Good morning Sreetips. I've been looking forward to this video. Now I'm looking forward to those solids that didn't make it through the Strainer. Cool stuff my man...
Asked a question about centrifugal filters and some one mentioned a centrifuge . What I was trying on get to was repurposing a truck centrifuge oil filter or some of the old metal working machines used centrifugal filters. These would remove almost all of the particles as long as not in an acidic solution.
I wish i wouldve had science teachers that made science as fun and fascinating as some of you fellers on youtube do. Seriously, its so fascinating to me to see you take papers and extra pure gold from it.. i figured it wouldnt be much worth saving at all.. shows how much i know lol
Good evening Mr Sreetips, a little south from our friend David below 😊 QQ if you don't mind. Just as disclaimer, the volumes you process are exponentially higher than mine. I am pouring my recovered Silver to 300g and 700g bars for optimization reasons, in my case filter papers and detricts (ruble from placer gold or gold filled scrap) really make a difference for me. I always process Silver apart from anything else, even as stock pot I have one for Silver waste only. The thing is, the material I process for gold always carry Silver that ends up in the form of Silver Cloride mixed up with detricts, droppings and rejects. At the end of the day, burn after burn, filtration after filtrstion, filtering after filtering all is left is carbonized plastic and organic material, several forms of dirt, and sundry trash detricts. The issue I learned is, if I accumulate this dirt black goo, it will contain reasonable amount of Silver Cloride. I once ran lye and sugar on the goo with acceptable but unjustifiable results because of the further rework of.the recovered cement Siver. From the metalurgic books from college that have been useful for me when messaging different alloys for my metal bars collection, there is a whole annex dedicated to "the solubility of Silver Cloride". Have you ever even have a slight thought about the Silver Cloride that likely just go to trash or for you it is unworthy to waste time since you already process ~60Kg of the purest Silver crystals in the world. Today while refining Silver filter papers, spilled Silver blobs from poring or smelting, e waste Silber, etc (I needed slightly over 100g of Silver of pour my last 700g bar). At the end I recovered ~20g of Silver from the goo, slag, and droos. It is relevant for me (the chemicals needed to separate Silver from the contaminated Silver Cloride is cheap. Wonder if you ever care for those. Cheers mate!!!!! Filter paper and stock pot defining are my faces by far.
i think you could have simplified the step in which you rinse the solids to get the dissolved gold out, which you stated gives diminishing returns, and also get much more out of those solids. rather than washing the solids while still in the filter paper, you could just dump the solids into a beaker with distilled water, stirred a bunch, let the solids settle, and then decant the beaker into the one containing your gold solution, and THEN filter the solids 1 more time, and you wont need to struggle with washing under vacuum and diminishing returns at all.
Great video! If I may have 2 recommendations to make your filtering much faster. You can use a plastic door mash cut out exactly to fit in between your filter paper and your funnel that will create More air flow. You can also use diatomite filtering media On top of your filtering paper so it does not clog up fast. You can also use fiberglass filtering paper to filter your gold at the end of your process so you end up with very dry Material with fiberglass filter paper that you can melt together. I enjoy your videos very much keep up the good work!
Quite a few decades ago, I did a somewhat similar experiment, to your silver cement process. I had a small amount of silver nitrate solution. (About 1 teaspoon or so.) I stuck a piece of copper wire in it,and saw the silver "plating" the wire. I next stuck a nail in it. The copper "plated" the nail. That had to be about 50 years or so, ago. steve
hello Sreetips, at 13' you don't need to filter the whole beaker, just pump (and filter) the liquid containing the nitric from above, and rinse it two or three times since you are going to be making aqua regia just after.
I think the third step after charring and grinding should have been to burn it again with the electric furnace to get rid of all the carbon. That would reduce the amount of solids a lot and make the gold extraction and filtration much easier.
It surely pays to not be wasteful. Maybe someday you could make a video on the importance and proper ways to maintain equipment some of these folks may not appreciate what goes on behind the scenes.
Need some of those larger paper bags they have for leaves at some hardware stores or boxes you can fit a plastic bag around. While it probably doesn't amount to much, looks like there were some material that dropped off or blew away.
I wish you would have allowed the time lapse to slow down so we could appreciate the different colored flames. Green fire is, and always will be an absolute trip.
Need a longer stir stick! Another way to reduce low strength material like ash, is to place it in a plactic jarwith a couple ball bearings, and shake the 'sugar' out of it! 😊
This is all new to me, but I want to learn, I'd be silly not to as someone who knows. What video/method do you recommend for refining computer etc gold to a saleable item. I'm in Australia and things might be a different name over here, but I'll sort that out, it's the most low cost but still getting the right end result that matters to me and thank you from the global guys who have an interest in this. YOU ARE GREATLY APPRECIATED!!!!!!!!!!
Thank you. Computers have gold in them, but amount is tiny. Gold recovery from computer scrap is possible using acid/peroxide to dissolve the base metals under the gold contractors thus releasing the gold as a thin foil. The thin gold foils can then be recovered and refined. The gold foils are not pure gold.
It's always a pleasure to watch you in action, once again turning trash into treasure. Out of curiosity, how much silver do you end up recovering from a filter run like this? I'm presuming that more of the value from this process is in that gold button, but I still end up wondering at the whole picture of what all you managed to extract.
Thanks for all this interresting informations. Are you using Urea to Denox your solution before adding SMB or it's not needed ? Best Regards, Sylvain (from Belgium).
thats awesome most people would of thrown those filters away and not even think about it I didn't think you was going to get that much gold out of them and thats not even counting whatever else you get out of them silver , ect God bless you and your family my friend
Only the clueless would throw away those materials. I worked in the check lab for a world scale gold company doing fire assay analysis for 8 hours a day, day in, day out on 30 g ground rock samples. We’d inquart whatever gold was in the rock with 10ml of 0.1M AgNO3. After cupellation, we’d hit the dire bead with HNO3. We’d get several mg of gold, that we’d weigh record and then dump into a receiving vial. We had to run the samples anyway, so why not keep the gold. It’d take years to gather an ounce. No rush. And we’d recover the inquarted Ag as the chloride. No valuable metals went to the drain.
Nice work. Have a questions. Nitric in the begining y got silver using copper ... and paladium?? It should be diluted with hot nitric as well?? Also tge residues left in the filter after AR its papper filter ashes and what else?? AR didnt attack iridium or rhodium or it did?? And iron and base metals ???
Hot dilute nitric dissolves copper, silver, palladium. The ash cake will contain gold and possibly iridium and rhodium. Rh & Ir are not very soluble in AR.
@@sreetips I was thinking about Iridium, checked some sources and there might also be Rhodium and Osmium. As you have been reclaiming Pt from Pt/Ir alloys, I'd say Ir is about a certainty.
Thank you for sharing such an interesting video. I understand refining precious metals involves lots of things and it take a lot of time. But you’re doing it patiently for us. And, that makes me not to complain about length of your videos. In reality long videos help us to get more knowledge what could have been skipped in short videos. Just a suggestion if you can also perform purity test after recovering the metals. 🙏🙏
I'm betting that some of the chunks that were too big for the strainer contain lead and other metals with lower melting points. While lead isn't terribly valuable, it'd be fascinating to see how much accumulates throughout your refinings.
Somthing again from what you could think is nothing but to the trained eye not a micron has been missed very interesting yet again thankyou for your time and the effort that is a nice weekend up the coast for you and the wife in the value of this bitten you recovered again very interesting
Good morning and thank you for all the videos! One question. I have some cement silver that is contaminated with a bunch of copper. Do I need to melt it into shot to refine it or can I just go for the acid and refine it again?
I will saynu got me interested in this ..they really didn't have it in school high school anyway a computer room was our break through tech in that day lolo but u got me interested in it that's for sure u gonna help me make my life better and don't even know it lolo well I think ya do hahah thank u soon much for the knowledge
I have watched many video they are all great, I have seen question why after adding the acid and after the initial reaction the fumes are a cinnamon color? Thanks
Question for you. I'm not sure if you did a video on what supplies you need to start refining metals. ( Or what you need in your shop). Can you tell me what video it is or if your going to put one out. Thank you again for getting me so interested in Chemistry. 😎👍🇨🇦
I’ve included as much detail as possible in my videos. When I first started refining in 2010 there were crude videos that contained bits and pieces. They left out critical details with references to web sites that gave the rest of the information for a fee. Part of the reason I started making videos. To clear up the garbage that was being offered. I only wish that complete and comprehensive videos, like mine, were available back when I first started refining. I’d recommend watching and taking notes. It’s all in there, I’ve left nothing out.

I love watching the skill, if you remember someone said weeks back next, he will be showing us how half ounce of gold could be extracted from the filters. lol you ask he showed you how
Dear Sir, the gold melted in Aquarija'ssolution and you precipitated withmetasulfite, but you did not get rid ofthe nitric. Did you get rid of the nitricbefore precipitating? Please,I want ananswer from you. I am very excited tofollow you...Thank you. Mohammed..
after collecting alot of the refining residue, id suggest either burning it completely or using piranha solution on it to remove all of the carbon, it appears it carries 90% carbon after all. it would definetly help with refinment

I am pouring my recovered Silver to 300g and 700g bars for optimization reasons, in my case filter papers and detricts (ruble from placer gold or gold filled scrap) really make a difference for me.
I always process Silver apart from anything else, even as stock pot I have one for Silver waste only.
The thing is, the material I process for gold always carry Silver that ends up in the form of Silver Cloride mixed up with detricts, droppings and rejects.
At the end of the day, burn after burn, filtration after filtrstion, filtering after filtering all is left is carbonized plastic and organic material, several forms of dirt, and sundry trash detricts. The issue I learned is, if I accumulate this dirt black goo, it will contain reasonable amount of Silver Cloride.
I once ran lye and sugar on the goo with acceptable but unjustifiable results because of the further rework of.the recovered cement Siver.
From the metalurgic books from college that have been useful for me when messaging different alloys for my metal bars collection, there is a whole annex dedicated to "the solubility of Silver Cloride".
Have you ever even have a slight thought about the Silver Cloride that likely just go to trash or for you it is unworthy to waste time since you already process ~60Kg of the purest Silver crystals in the world.
Today while refining Silver filter papers, spilled Silver blobs from poring or smelting, e waste Silber, etc (I needed slightly over 100g of Silver of pour my last 700g bar).
At the end I recovered ~20g of Silver from the goo, slag, and droos. It is relevant for me (the chemicals needed to separate Silver from the contaminated Silver Cloride is cheap.
Wonder if you ever care for those.
Cheers mate!!!!! Filter paper and stock pot defining are my faces by far.
That's quite a bit of gold to just come out of some filter papers, nice work. 👏
i think you could have simplified the step in which you rinse the solids to get the dissolved gold out, which you stated gives diminishing returns, and also get much more out of those solids.
rather than washing the solids while still in the filter paper, you could just dump the solids into a beaker with distilled water, stirred a bunch, let the solids settle, and then decant the beaker into the one containing your gold solution, and THEN filter the solids 1 more time, and you wont need to struggle with washing under vacuum and diminishing returns at all.
You gots to have a passion for it, a labor of love!👍
I sometimes wonder, " Is it really that important to keep all those filter papers?". Yes, it is, thanks Sreetips for another great video.
What type of filters are these?
Whatman lab grade filter papers.
Great video! If I may have 2 recommendations to make your filtering much faster. You can use a plastic door mash cut out exactly to fit in between your filter paper and your funnel that will create More air flow. You can also use diatomite filtering media On top of your filtering paper so it does not clog up fast. You can also use fiberglass filtering paper to filter your gold at the end of your process so you end up with very dry Material with fiberglass filter paper that you can melt together. I enjoy your videos very much keep up the good work!
Quite a few decades ago, I did a somewhat
similar experiment, to your silver cement
process.
I had a small amount of silver nitrate solution.
(About 1 teaspoon or so.) I stuck a piece of
copper wire in it,and saw the silver "plating"
the wire. I next stuck a nail in it. The copper
"plated" the nail.
That had to be about 50 years or so, ago.

hello Sreetips, at 13' you don't need to filter the whole beaker, just pump (and filter) the liquid containing the nitric from above, and rinse it two or three times since you are going to be making aqua regia just after.
I think the third step after charring and grinding should have been to burn it again with the electric furnace to get rid of all the carbon. That would reduce the amount of solids a lot and make the gold extraction and filtration much easier.
It surely pays to not be wasteful. Maybe someday you could make a video on the importance and proper ways to maintain equipment some of these folks may not appreciate what goes on behind the scenes.
These are very fun
The flame coming off the filter papers was very interesting. Blue and green flames indicate copper is in the filters.
Yes it's a bit of backyard gas chromatography!
@@AndyGraceMedia very entertaining.
A good look at the colours might give indications about other elements (including metals) as well.
Need some of those larger paper bags they have for leaves at some hardware stores or boxes you can fit a plastic bag around. While it probably doesn't amount to much, looks like there were some material that dropped off or blew away.
I wish you would have allowed the time lapse to slow down so we could appreciate the different colored flames. Green fire is, and always will be an absolute trip.
i love your channel. Always loved chemistry. It is exciting to see it being used in real life applications.
Need a longer stir stick! Another way to reduce low strength material like ash, is to place it in a plactic jarwith a couple ball bearings, and shake the 'sugar' out of it! 😊
This is all new to me, but I want to learn, I'd be silly not to as someone who knows. What video/method do you recommend for refining computer etc gold to a saleable item. I'm in Australia and things might be a different name over here, but I'll sort that out, it's the most low cost but still getting the right end result that matters to me and thank you from the global guys who have an interest in this. YOU ARE GREATLY APPRECIATED!!!!!!!!!!
Thank you. Computers have gold in them, but amount is tiny. Gold recovery from computer scrap is possible using acid/peroxide to dissolve the base metals under the gold contractors thus releasing the gold as a thin foil. The thin gold foils can then be recovered and refined. The gold foils are not pure gold.
@@sreetips So what vid would you recommend for the process of refining the pins etc to a pure ingot?
Gold plated computer scrap (gold plated on to a metal substrate) is best processed in a sulfuric acid stripping cell.
@@sreetips So sulfuric instead of nitric? is that do you have a vid on that and sorry for all the questions, but I respect your opinion.
It's always a pleasure to watch you in action, once again turning trash into treasure. Out of curiosity, how much silver do you end up recovering from a filter run like this? I'm presuming that more of the value from this process is in that gold button, but I still end up wondering at the whole picture of what all you managed to extract.
There was probably 2 or 3 ounces of silver
Definitely worthwhile processing thanks for sharing : )
The Point of Diminishing Returns. Nicely said, sir.
Thanks for all this interresting informations.
Are you using Urea to Denox your solution before adding SMB or it's not needed ?
Best Regards,
Sylvain (from Belgium).
None of the refiners I learned from used urea. I use incremental nitric dosing so there’s no nitric to remove (denox).
@@sreetips Thanks a lot for you quick answer.
It always astounds me that the torch and the flames don't cause gold powder to fly off!
a small extra yield from the melt dish ;) you always find a way to do two jobs at the same time. great job.
thats awesome most people would of thrown those filters away and not even think about it I didn't think you was going to get that much gold out of them and thats not even counting whatever else you get out of them silver , ect God bless you and your family my friend
Only the clueless would throw away those materials.
I worked in the check lab for a world scale gold company doing fire assay analysis for 8 hours a day, day in, day out on 30 g ground rock samples.
We’d inquart whatever gold was in the rock with 10ml of 0.1M AgNO3.
After cupellation, we’d hit the dire bead with HNO3.
We’d get several mg of gold, that we’d weigh record and then dump into a receiving vial.
We had to run the samples anyway, so why not keep the gold. It’d take years to gather an ounce. No rush.
And we’d recover the inquarted Ag as the chloride.
No valuable metals went to the drain.
Bravo!
Great Video again Sretips. Would it be worth experimenting with Lye to get rid of the wood pulp? Or am I talking out of the top of my head again? 😄
I’ve never used it
I was wondering how you did this process after watching you refined in the gold process. Great stuff :)
It’s amazing! Your a Gold scientist.
I’ve been waiting for this for so long! Thanks Sreetips!
Nice work. Have a questions. Nitric in the begining y got silver using copper ... and paladium?? It should be diluted with hot nitric as well?? Also tge residues left in the filter after AR its papper filter ashes and what else?? AR didnt attack iridium or rhodium or it did?? And iron and base metals ???
Hot dilute nitric dissolves copper, silver, palladium. The ash cake will contain gold and possibly iridium and rhodium. Rh & Ir are not very soluble in AR.
@@sreetips I was thinking about Iridium, checked some sources and there might also be Rhodium and Osmium. As you have been reclaiming Pt from Pt/Ir alloys, I'd say Ir is about a certainty.
Thank you for sharing such an interesting video. I understand refining precious metals involves lots of things and it take a lot of time. But you’re doing it patiently for us. And, that makes me not to complain about length of your videos. In reality long videos help us to get more knowledge what could have been skipped in short videos.
Just a suggestion if you can also perform purity test after recovering the metals. 🙏🙏
I'm betting that some of the chunks that were too big for the strainer contain lead and other metals with lower melting points. While lead isn't terribly valuable, it'd be fascinating to see how much accumulates throughout your refinings.
Somthing again from what you could think is nothing but to the trained eye not a micron has been missed very interesting yet again thankyou for your time and the effort that is a nice weekend up the coast for you and the wife in the value of this bitten you recovered again very interesting
Good morning and thank you for all the videos! One question. I have some cement silver that is contaminated with a bunch of copper. Do I need to melt it into shot to refine it or can I just go for the acid and refine it again?
I’d dissolve in hot dilute nitric, then cement the silver out on copper.
I will saynu got me interested in this ..they really didn't have it in school high school anyway a computer room was our break through tech in that day lolo but u got me interested in it that's for sure u gonna help me make my life better and don't even know it lolo well I think ya do hahah thank u soon much for the knowledge
I have watched many video they are all great, I have seen question why after adding the acid and after the initial reaction the fumes are a cinnamon color? Thanks
Looks like NO2 gas.
Question for you. I'm not sure if you did a video on what supplies you need to start refining metals. ( Or what you need in your shop). Can you tell me what video it is or if your going to put one out. Thank you again for getting me so interested in
Chemistry. 😎👍🇨🇦
I’ve included as much detail as possible in my videos. When I first started refining in 2010 there were crude videos that contained bits and pieces. They left out critical details with references to web sites that gave the rest of the information for a fee. Part of the reason I started making videos. To clear up the garbage that was being offered. I only wish that complete and comprehensive videos, like mine, were available back when I first started refining. I’d recommend watching and taking notes. It’s all in there, I’ve left nothing out.
@@sreetips Thanks for replying and I'll be sure to watch more of your videos and take notes. 👍😎🇨🇦
In a nearby universe, there is an app call MePipe, where a creator called roadclues extracts pure filter paper from gold bars.
سيدي العزيز . كيف قمت بالترسيب بالميتا سليفايت قبل ان تتخلص من النتريك في محلول أكواريجيا هل حايدت النتريك قبل الترسيب ارجوك اريد اجابة وانا متحمس جدا لمتابعتك شكرا . محمد...
Yes
I love watching the skill, if you remember someone said weeks back next, he will be showing us how half ounce of gold could be extracted from the filters. lol you ask he showed you how
Dear Sir, the gold melted in Aquarija'ssolution and you precipitated withmetasulfite, but you did not get rid ofthe nitric. Did you get rid of the nitricbefore precipitating? Please,I want ananswer from you. I am very excited tofollow you...Thank you. Mohammed..
I added just enough to just dissolve the gold. So there’s no excess nitric to get rid of.
Why am i so adicted to watching these damn videos? great work bro
That flame colour is so pretty
"Plus and minus kitchen strainer. Nice"---Something Chris would say.
Fascinating, ty for educating me
after collecting alot of the refining residue, id suggest either burning it completely or using piranha solution on it to remove all of the carbon, it appears it carries 90% carbon after all. it would definetly help with refinment
😍😍 loving these videos!!
Nice work thanks well brvo my friend
