The one off the back, but there was also a small chunk near the front bottom corner. Then you could see all the gold drops along the sides of the melt dish. A little borax along the sides and he might get a gram or so out of that melt dish.
Did you notice the pan doing a little jiggle back and forth as the gold was drying? See at 5:00 when you remove the water. That jiggle comes from the heating coil on that hotplate. It turns on and off maintaining a certain temperature and when it heats and cools it expands and contracts moving the pan back and forth just a little as it does so. You would never see it without time-lapse. Another great series, Sr. I thank you again for sharing your hobby with all of us. It never gets old.
@@sreetips Pls help i need advice..Im new at this but was fasinated by few vids back you growing the silver and im a rookie and wanna start doing the same so equipment wise looks like your using a laboratory power supply found one on ebay is a maximum of 30V 10A DC Power Supply Adjustable 4 Digit Display Laboratory Power Supply..Also you said you were using nitric acid but what percentage is that?..Because the ones i can find online is rated at 68% so will that be suitable and what outher acid where you using might have been sulphuric also what percentage?..Im a total rookie at this but really wanna learn but not die in the process anything you can tell me chemicals percentages would be awesome..Looks like it uses a really small amount of electricity as well for being left on 24/7 so i can't see it hurting the power bill too much as well..We all gotta start somewhere and just in the learning stage appreciate any help thanks
You drop a bit of gold at 5:45 and you never show yourself picking it up. This made me feel uncomfortable. Please confirm that the bit of gold was retrieved.
Yea, Big chunk at 5:45 and a small piece at 8:40 as he's loading up for his 3rd pour. Plus, he left a lot of gold beads in the dish, and also poured off lots of floating gold into that orange bucket. Never fear however, that's just a guarantee you'll see another video of him recovering it.
It could've been those pieces that spilled over the melt dish that cost you...and a little pour over into gold waste container. I suspect you'll get it in the end.😅
You are welcome. There was more vapour from the precipitate, while being heated in the melt dish, than we usually see. Spectacular bars! Thank you Sir. 👍👍🤟
Adding the note here now... @sreetips since it smelled like wood I am going to guess it was sulfur dichloride. Was there briefly a cherry red liquid? No, I did not see that since it was dry enough so that makes the allotrope a whitish gas and pungent like burning wood! Bingo! That is what it was, not trapped H2O in the powder gold at all. I stand corrected from my earlier comment of it being just traped H2O. It was trapped SCL2 (g). That is a nasty gas, would have been better to have your respirator on you old salt dog! It forms chlorine containing acids on contact with your damp mucous membranes and as a red liquid rather than a whitish gas is highly corrosive and toxic. As a gas it did little harm if you rinse your nose and mouth with 1/2 normal saline and an infant nose syringe made of soft rubber or now a days silicone -if not done you will have a bit of membrane peel and that would be the extent of it over the few times you were exposed, take care in the future to pulverize any gold sponge better while drying please or use a respirator as you have in the past. That explains the thick whitish gas discharged several times, make a note in the book so someone else reading it will be warned as well. Folks, all is well, this (gas precipitation) is the best method, still, it was a lesson for ALL. That is a great camera and lighting when I went back and looked it is just as I have heard it described by and in my uncle's crabby hand written notes.

I don't know what you were doing camera-wise with those close-ups of the gold melting in the melt dish, but I have to say that there's a beautiful artful quality to the video. Maybe it's the saturation of colors or some other strange artifact of the video settings within the camera, but I haven't seen such a visually satisfying sequence in a long time. I would call it real art. Well done.
I love all your videos. I am sitting here trying to think of how you can get more views and what other content you can do that fits into what you've already done. Gold videos: 1) extract gold from ore. 2) refine gold that was found in the ground (like from panning) 3) improve refining methods from the high view videos (gold fingers, computer scrap, plated stuff) Silver Videos: 1) automate silver refinement (maybe a screw conveyer or an auger that gets the silver out so it wont short), this might lead to different container shapes. Other videos: 1) Do amateur chemistry to make the chemicals you then use to refine gold/silver 2) jewelry prep. make improvements to speed/quality? 3) get copper out of waste solution and make something to sell to us. If I think of more I'll post in whatever the latest video is.
Makes me wish id av studied science at school..ammount of gold ive thrown away over years getting rid of old circutboards in computers and nackered mobiles etc..
I must say I’ve wondered how beautiful a “ gold cell “ of equal proportion as your old silver cell would look at harvest time I know that has to have crossed everyone’s mind and also since I’m asking this hypothetically would you feed 10k 14k etc through it ? And of course would it grow an insanely beautiful crystal forest? Hmm 🤔 I wonder 💭
There’s a way to grow high purity gold crystals. But it’s complex and requires special apparatus. I can grow pure four nines gold in my electrolytic gold cell. But the gold doesn’t look the same as the silver crystal does. It’s more nodular. But still beautiful in its own rite.
At the end when you showed the losses and explained that something in the K gold must have been non gold, is a great example of the reason to hobby refine. I bet there are a lot of folks who hold their gold as karate scrap but have a lot less gold than what they think they do. Great refining series. I have a video request, can you do an in depth review of all the components you use to assemble the SO2 generator?
He was relocating some of the gold during rinsing and pour offs into the waste refining stock pots, eventually that will be recovered, but to me that is a waste of time and resources if you've already got the gold nearly pure to pour it off into a lesser pure mix then means you are wasting that effort. Instead to pour it off into one dedicated container to let it settle out and then after it has settled out you could pour that solution off, but i think that would be a good base to see if you could work with just that solution to get the gold out without recontaminating it with other metals. I'm not sure how that would go, but perhaps some aquaregia and then an SO2 bubble precipitate... Also I've already mentioned that he's wasting a fair amount of nitric acid in later boils and rinses that could be reused for his initial acid boils. Pouring that into a silver stock pot loaded with sterling silver is a big waste of time and effort because later he's having to reprocess the silver out of those solutions again. Getting huge buckets of cemented silver to then reprocess again to remove the copper and other metals. Just adding extra work for himself. Sorry to harp on this, but I think it important to be efficient with time and resources. :) And sure if you are happy with what you are getting than you can easily ignore my thoughts, but for others who are reading along I think it worth to think about. I think of it this way, when working on a project I don't want to introduce more Gremlins by making it more of a mess. In gardening this means weeding from the uphill and upwind areas (energy and time flows and edges are important). In metal refining it means not doing things that push your results backwards towards the other contaminants if you can help it.
Great video as always! Hey, if you're looking for an idea for a video, I personally, would find something like this very interesting.: Before you begin, weigh everything, the jewelry, your jugs of acid, your water bottles for rinsing, your waste container, your silver/base metal container, etc., etc. etc. And then after all is complete, weigh everything again and see if there is a proper accounting for all the mass. Just wondering if maybe you could get an idea of how much of the mass is leaving via that brown vapor during the dissolving process and how much silver/base metals was recovered, etc. I'd imagine you might have to do some intermediate weighings too. For example, when you're drying the gold powder maybe you'd want to weigh it wet before drying so you know how much of the water you used from your water bottles for rinsing just went up in steam, as opposed to going into one of your waste receptacles. I don't know, maybe just me, but I think that would be kind of cool to see.
Let me tell you, I’ve experienced some spills recently, not much, but in refining every little bit counts. These never would have happened if that pesky camera wasn’t in my way all the time.
You're getting pretty good at pouring ingots, they turned out nice. I do enjoy that method of reanimation of the gold, for the same reasons as you. ✌️😎
Inquarted gold is easier to disolve and refine. With the silver in, the acids can really get in there and remove not just the silver but other metals and contaminants that might be present. He recovers the silver but not any of the copper, if I recall correctly. (The copper isn't worth it)
If he does not inquart the gold, aka adding silver, then the nitric acid is unable to pull the base metals from the gold and it will just sit in the acid inert. He does recover the silver later.
He uses copper later to take the silver out of solution. And then melts poor quality silver into shot and uses it in an electrolyte silver cell to get it .999 fine
Yeah, it’s a strange process to add silver than clean up everything with the silver in corded into the gold. I’ve asked the same question before it’s still strange to me, but some kind of molecular structure is easier to eat out with acid when the silvers attached to it.
Beautiful ending of the third part of your refining video! The walls of your working place must shine golden after so many years of gold smelting and the condensing gold vapors on the surrounding surfaces ! Do you also recycle your airfilters in your mask and aircon, similar to the jewler´s dust ?
Kevin, how long have you been collecting all of that lab-grade glass? You've got quite the collection! Would love to see another video where you show off your shop. Great video, my friend. Thank you!
I accumulated it over the last 14 years. When I thought of an experiment I’d figure out what glassware I needed, then went on eBay and ordered it. I had a small chemistry setup in my basement when I was about ten or twelve. But I abandoned it when I got in high school and discovered partying and girls. My current setup is a continuation of that time. Only now I can afford nicer stuff to practice with.
I've smelled H2S many times but I assume SO2 is more like a burnt match than rotten eggs. I assume they have the same effect in higher concentrations in losing sense of smell. I hope never to find out.
Call me crazy. But I've watched alot of your videos and this new method of refining the gold looks better. I noticed a slight difference. Looks better. Thanks again for your videos. 😎👍🇨🇦
I love your videos. I will never do any of this cuz I’m just not smart enough AND most importantly my wife wouldn’t let me even try. 😂 Regardless your videos are awesome and so informative. Love them.
Love your videos sreetips, they are fascinating to watch. Forgive my ignorance but is this refining process considered alchemy/transmutation or chemistry or is it kinda both? Thank you 👍
It’s all pretty much the same process. Cement out the precious metals on copper in the stock pot, transfer the copper nitrate from that to the bucket full of angle iron to cement out the copper. Then all I have is an acidic iron solution. Add NaOH to pH9 to drop metal hydroxides, filter out the metal hydroxides, raise filtrate to pH7 (almost drinkable) then add to the normal waste stream. Nothing acidic or harmful gets poured down the drain or in the toilet.
@@sreetips at that point then it's safe for the drain. I'm almost at the point of trying this process just working on the beakers and molds. I've been collecting sterling silverware and a bunch of other stuff for silver shots. Just want to make sure I get it all down right but I'm sure I'll be making a few mistakes along the way
Sreetips, did you look into getting the gold powder under a microscope at the university yet. I know you're a busy man, but would love to see it happen.
What, times 0.583, equals 6 ounces? 6 divided by 0.583 equals 10.2 Troy ounces of 14k gold. 10.2 Troy ounces times 31.1g equals about 320g of 14k scrap gold to get 6 Troy ounces of pure gold.
Awesome video as always Sreetips but I was wondering do you know of any other precious metal refining channels besides yours I've been looking all over.
I sure hope you see this, I can't think of anyone else that might know the answer. I have an old gold plating kit from the 60's. Or early 70's , the 4oz bottle of plating solution leaked and soaked into about a 8 inch section of the cardboard, would you have any idea how I might be able to salvage it? Would there even be enough in it to be worth bothering with?
I’ve no experience with gold plating solutions. But if it were mine, I’d cut the cardboard with the gold plating solution out, burn it to an ash in a melt dish, place the ash in a clean beaker and try a little Aqua Regia to see if I could detect and gold in the solution.
If I had the inclination to repeat this myself, my main concern would be the health implications. Can it be reduced to zero essentially. Okay, we won't live forever, and everything around us is contaminated nowadays, but how can we be 100% sure that we won't harm ourselves doing this. A closed laboratory fume hood with the built in gloves comes to mind. Or robotics, but that seems almost impossible. Well, there are some advancements in the field, but even if possible technically, probably prohibitive by cost.
You got to find a better way to put the gold in the melt dish. It's too easy to spill it all over the place. I've seen so many chunks not make it into the melt dish. It's either that or try to find a bigger melt dish.
Awesome mr Sreetips....beautiful 999 gold a great precipritation....your work is amazing and great science aswell love your chanel mr Sreetips greetings from the Netherlands
Hello Mrs and Mr Sreetips. Early morning here in Norway today. The sun is already shine this summer day. I have many clip to see from you🔥🌺🌺 Hope you both have a lovely day 🙂 God bless your humble hart🔥 Arne
Nice. Takes 16.5 ounces of gold to buy the Dow. Last week it was 16.7 ounces to buy the Dow. That means that, priced in GOLD, the Dow was down this week. Even though it made a new high. Making predictions is risky business, especially if they’re about the future. I predict one ounce of gold to buy the Dow.
Afternoon there Buddy! Just an FYI! 55 Gallons of 70% Fuming HNO³ for $2,800.00 DELIVERED. NO HAZ FEES, though May. "Allied Chemical". Might want to check it out? 55 gallons? That might keep you for a month or two? 😅 I'm going to go for it! My Laboratory is in a 30' x 40' building, out in the country. Plenty of room for a 55 gallon drum! Have a great day, Gunny! Wade
That’s a little bit too much for me to store. I get six bottles every six months or so. That suits me fine. I’m just a hobby level refiner. I remember 14 gallon carboys of nitric for about $400 with a $200 deposit for the stainless keg (carboy). But even that would be way too much for my small hobby operation.
@@sreetips I suppose that you are right. I'm nowhere near your level of production. I hate for it to be wasted. They also have great prices on case lots of 2.5 litter bottles. $335.00, I believe it was. No shipping or Haz fees trough May, as a promotion. New customer's get an additional 10% off. Think I'll give them a try. $335.00 for 15 litters is a pretty good price. Thanks Gunny! Wade
@@sreetips You know, I was looking for vessels that could withstand the centrifugal forces of a centrifuge. Those, "Carboys", sound exactly like what I'm looking for! I figured that instead of waiting for gravity to drop parcipitate, I'd speed things up a bit? Thanks a second time, Gunny! You are truly AWESOME! Wade
@sreetips hello my friend. Thankyou for the series. Quick question for you. I was down to my brown mud I then dried it out. Put it in my crucible and started to put heart on it sprinkle a little borax. But it never became a molten puddle and just crystalized? For lack of a better word. Any idea what I did wrong?
How many of you all noticed that chunk of gold sponge fall out his melt dish?
The one off the back, but there was also a small chunk near the front bottom corner. Then you could see all the gold drops along the sides of the melt dish. A little borax along the sides and he might get a gram or so out of that melt dish.
Yes
I’ll get it and add to my next batch of karat gold - no worries.
I was just thinking, “There’s $30 just sitting on the brick…”
Ya I was wondering about that 🤔 lol
Did you notice the pan doing a little jiggle back and forth as the gold was drying? See at 5:00 when you remove the water. That jiggle comes from the heating coil on that hotplate. It turns on and off maintaining a certain temperature and when it heats and cools it expands and contracts moving the pan back and forth just a little as it does so. You would never see it without time-lapse.

Love watching your videos. They are addictive. Don't know why but it Never gets old. Must be the shiny yellow metal. Terrific content.

Your answer its in the fist video this serie.
haha, same. Also, this is my first time bother to read any comments on a sreetips video. Sree's got a high booty bot ratio.
Yep, I'd guess a 1 to 2g chunk of powder. There was also a smaller piece that fell off to the left in the last batch he put in the dish.
Yea, Big chunk at 5:45 and a small piece at 8:40 as he's loading up for his 3rd pour. Plus, he left a lot of gold beads in the dish, and also poured off lots of floating gold into that orange bucket. Never fear however, that's just a guarantee you'll see another video of him recovering it.
These uploads are a perfect example of why i watch your videos. Pefecting techniques keeps you ahead of the game, and saving time. Amazing

Would love to see more vids on buying gold and silver and the total cost breakdowns
He won't do that. He avoids those details to protect the system that he and his wife have of acquiring the material they refine for themselves.
I’ve tried to convince Mrs sreetips to let me shoot video of her in action. But she refuses because it very cut throat. And I must respect her wishes
Great result and some nice little bars!
that new beaker is massive I love it the gas precipitation it the best love the way the gold comes out so clean👍
i think the hydrogen proxied gas precipitation makes the cleanest. that i have seen you do so far.
H2O2 dissolve, SO2 gas precipitation. A good combination for pristine GOLD.

@5:45 That was a big chunk dropped
Don’t fret, I retrieved it.
3 videos, total process took some time, the yield: perfect. Minus the iron from that O2 process. Loved it, Sreetips is where to get gold from.
3 very beautiful bars of gold. 👍🏻

Really great! I noticed when you were melting down the silverware a couple pieces seemed harder to melt maybe they were silver coated metal
It was all 800 parts per thousand silver flatware.
Always Perfect work you do
This never gets old, Thank you Sreetips!

Sreetips, that's not a Beaker, that's a 45 Gallon Drum dude! I love the way you roll my man 🙂
Oh my god, the golden chocolate. What a sight.❤
Sreetips, little hunk-a-gold powder flew into the thermal blanket @ 8:40 . Don't forget to collect it.
Ok
did you get that gold that tried to escape out of the dish
I should have noted it in the video. I knew that there would be many comments about that and the other crumbs that escaped.
At 8:43 a smoke comes from the melting dish. Could you describe that smell?
It smelled like burning wood.
I hope that you are wearing a respirator for this! Sometimes the out gassing from those melts is intense!
0:58 I almost choked on my Reese’s puffs when the video sped up and I thought there was going to be a spill! 😅
Let me tell you, I’ve experienced some spills recently, not much, but in refining every little bit counts. These never would have happened if that pesky camera wasn’t in my way all the time.

Great series, again! Love to watch.
@5:45 Hey if you want to do your gold melt videos in my garage.... let me know!
You're getting pretty good at pouring ingots, they turned out nice. I do enjoy that method of reanimation of the gold, for the same reasons as you. ✌️😎
why did he have to use all that silver to start with? and can he recover that or does it go to waste? just curious
He doesn’t waste anything. He recovers all the silver, and silver is what he uses to extract the gold.
Inquarted gold is easier to disolve and refine. With the silver in, the acids can really get in there and remove not just the silver but other metals and contaminants that might be present. He recovers the silver but not any of the copper, if I recall correctly. (The copper isn't worth it)
If he does not inquart the gold, aka adding silver, then the nitric acid is unable to pull the base metals from the gold and it will just sit in the acid inert. He does recover the silver later.
He uses copper later to take the silver out of solution. And then melts poor quality silver into shot and uses it in an electrolyte silver cell to get it .999 fine
Yeah, it’s a strange process to add silver than clean up everything with the silver in corded into the gold. I’ve asked the same question before it’s still strange to me, but some kind of molecular structure is easier to eat out with acid when the silvers attached to it.
Beautiful job as always!
That beaker is comically huge. We need more of it.
Is it time to process all your Gold Waste Solutions ?
Stock pots are due. Filters are full.
Beautiful ending of the third part of your refining video! The walls of your working place must shine golden after so many years of gold smelting and the condensing gold vapors on the surrounding surfaces ! Do you also recycle your airfilters in your mask and aircon, similar to the jewler´s dust ?
I’ve never tried it.
Wow, those pours were so damn precise!
I’ve found that the key is getting that graphite mold real hot.

I’m using a fused silica melt dish to melt the gold “dirt”.

Kevin, how long have you been collecting all of that lab-grade glass? You've got quite the collection! Would love to see another video where you show off your shop. Great video, my friend. Thank you!
I accumulated it over the last 14 years. When I thought of an experiment I’d figure out what glassware I needed, then went on eBay and ordered it. I had a small chemistry setup in my basement when I was about ten or twelve. But I abandoned it when I got in high school and discovered partying and girls. My current setup is a continuation of that time. Only now I can afford nicer stuff to practice with.
ممكن سؤال كيف ترسب الذهب ماهي المواد ترسيب أنا عبفشل في الترسيب شكرا الك
We buy scrap gold jewelry at local sales near our city.
I've smelled H2S many times but I assume SO2 is more like a burnt match than rotten eggs. I assume they have the same effect in higher concentrations in losing sense of smell. I hope never to find out.
Enjoy the content! Thank You Sir!
I wonder if any combustion products from the torch end up in the metal, reducing the purity. Vs melting with electric heat.
None that report in an assay. The gold comes back three nines - every time.
@@sreetips Really impressive that some home chemistry with careful technique yields such a great result!
Looks like you are using a propane torch to preheat the mold and a cutting torch to melt. Is that oxy acetylene or oxy propane?
MAP torch to heat the mold. Oxy/acetylene with a cutting head for the gold melt.
@@sreetips Thank you Sir!
Thank you for teaching.
Call me crazy. But I've watched alot of your videos and this new method of refining the gold looks better. I noticed a slight difference. Looks better. Thanks again for your videos.
😎👍🇨🇦
I meant to ask yesterday.
What is the reaction?
SO2(g) + AuX (X= 2NO3- or 2Cl-) --> Au(s) and?
Its SO2(g) + AuX (X= 2NO3- or 2Cl-) --> Au(s) = GOLD
@@UncalBertExcretesThe reaction doesn't just produce gold it produces silver chloride. IE the red vapor coming out of the top of the beaker
@@UncalBertExcretes We're both missing the other half of the reaction....
You guys know way more than I do. All I know is I bubble the gas and the gold comes out of solution - like magic!
@@uwillnevahno6837 Ag(s) + AuNO3(aq) → Au(s) + AgNO3(aq). Sorry my man it's silver nitrate not silver chloride.
Just pour it in the next mold over maybe?
I was pouring another 100g gold bar last week and somehow i dumped it all over my melt talble and floor im still missing about 2 grams
Thankfully, that’s never happened to me (knock on wood). Still, if you got everything back except two grams, then that’s not bad.
Last night I took a shop vac an vacuumed the whole lab thin panned it out an there was way more than 2 grams! There was almost 8!
Nice!
Love this content so much Sreetips! Where does all that waste solution go? To a waste management place?
Waste treatment is easy and cheap.
I love your videos. I will never do any of this cuz I’m just not smart enough AND most importantly my wife wouldn’t let me even try. 😂 Regardless your videos are awesome and so informative. Love them.
When you’re rinsing the gold sponge at the beginning, is there a purple tint to the rinse water? Is that gold in the water?
Yes - purple is the color of colloidal gold.
@@sreetips maybe that could also account for the missing ten grams, between that and the two chunks that fell out of the dish I mean.
Very nice. You give me the urge to invest in some equipment and set up my own personal refinery. Where do you get rid of all your dirty solution at?
Waste treatment.
What are the fumes coming off the gold when you melt it in the dish? Is that lost gold?
No, some compound from gas reaction. It smelled like burning wood.
Love your videos sreetips, they are fascinating to watch. Forgive my ignorance but is this refining process considered alchemy/transmutation or chemistry or is it kinda both? Thank you 👍
This is gold refining, pure and simple.
Did you do something different with the camera when you were melting this time around? That gold looked extra shiny under that blow torch buddy.
I had an extra light shining on it
Good series 👍
Thank you
So what do you do with all of the used up solutions from the silver and gold. How do you dispose of it .
Waste treatment.
@@sreetips that would be an additional cost per gallon am I right and would also depend on what chemicals
It’s all pretty much the same process. Cement out the precious metals on copper in the stock pot, transfer the copper nitrate from that to the bucket full of angle iron to cement out the copper. Then all I have is an acidic iron solution. Add NaOH to pH9 to drop metal hydroxides, filter out the metal hydroxides, raise filtrate to pH7 (almost drinkable) then add to the normal waste stream. Nothing acidic or harmful gets poured down the drain or in the toilet.
@@sreetips at that point then it's safe for the drain. I'm almost at the point of trying this process just working on the beakers and molds. I've been collecting sterling silverware and a bunch of other stuff for silver shots. Just want to make sure I get it all down right but I'm sure I'll be making a few mistakes along the way
Was wondering do you process your paper storage on camera or is that something you do off camera?
I’ve got a bucket full of filters that I need to process. I’ve done them in the past. Now they’re due again.
Sree.. you’re a wizard!
Thank you
I presume a gold waste recovery series is in order soon based on the amount of gold waste lately. 🤞
Stock pots are due
Sreetips, did you look into getting the gold powder under a microscope at the university yet. I know you're a busy man, but would love to see it happen.
Did u pick up the gold that fall to the side
Yes
Which method is cheaper to get all the materials/chemicals for, SO² or the other where you precipitate with stump out?
Stump out is easy and cheap but the gold will have salts in it. The SO2 gas is a little more time to set up and take down, but the gold is very clean.
How much material did it take to get that much in gold ?
What, times 0.583, equals 6 ounces? 6 divided by 0.583 equals 10.2 Troy ounces of 14k gold. 10.2 Troy ounces times 31.1g equals about 320g of 14k scrap gold to get 6 Troy ounces of pure gold.
Awesome video as always Sreetips but I was wondering do you know of any other precious metal refining channels besides yours I've been looking all over.
To be honest, mine is the only one I watch.
@@sreetips gotcha thank you Sir
❤اصبحت عظوا من متابعين قناتك الراقيه ❤
Thank you and welcome!
I sure hope you see this, I can't think of anyone else that might know the answer. I have an old gold plating kit from the 60's. Or early 70's , the 4oz bottle of plating solution leaked and soaked into about a 8 inch section of the cardboard, would you have any idea how I might be able to salvage it? Would there even be enough in it to be worth bothering with?
I’ve no experience with gold plating solutions. But if it were mine, I’d cut the cardboard with the gold plating solution out, burn it to an ash in a melt dish, place the ash in a clean beaker and try a little Aqua Regia to see if I could detect and gold in the solution.
Amazing gold bars, great job sreetips 👍
Beautiful bars!
Did you retrieve the chunk that fell out of your spoon at 5:47?
No, I just let it go. It’s lost and gone forever! I’m being facetious, swept it into a container and will add into my next batch of karat scrap.
Well you also lost 2 clumps in the scoop process... not sure what that weighed but at least 5g....
Say, why is the dried gold mud stuff you melt so non-dense? Is it some kind of sponge or something?
Pure gold sponge.
@@sreetips Huh. That's funny. How does it turn into a sponge?
Porous and spongy form of metallic gold

Hi sreetips, can you put a educational video over recycling of dead celk phone lithium batteries and also document the ROI
Unfortunately I only work with gold and silver. No experience with dead cell phone lithium batteries.
Awesome videos and absolutely beautiful gold bar's thanks for sharing sreetips
If I had the inclination to repeat this myself, my main concern would be the health implications. Can it be reduced to zero essentially. Okay, we won't live forever, and everything around us is contaminated nowadays, but how can we be 100% sure that we won't harm ourselves doing this. A closed laboratory fume hood with the built in gloves comes to mind. Or robotics, but that seems almost impossible. Well, there are some advancements in the field, but even if possible technically, probably prohibitive by cost.
There’s no way to safely do these reactions without a fume hood.
3 lovely gold bars!
You got to find a better way to put the gold in the melt dish. It's too easy to spill it all over the place. I've seen so many chunks not make it into the melt dish. It's either that or try to find a bigger melt dish.
I used an undersized melt dish because that’s all I had for now. Plus, the pesky camera is right in my way and hinders my movement and accuracy.
@@sreetips no worries, I wasn't trying to tell you what to do, I was just trying to help, sorry If I seemed intrusive.
Not at all. I read these comments and pick up ideas from my viewers.
I still think a small Mason jar full of sponge gold would be cool... lol
A large mason jar full would be cooler lol 👍
What grade of gold???? Is this 24k pure gold??????
Yes
Awesome mr Sreetips....beautiful 999 gold a great precipritation....your work is amazing and great science aswell love your chanel mr Sreetips greetings from the Netherlands
Thank Netherlands.
Hello Mrs and Mr Sreetips.
Early morning here in Norway today.
The sun is already shine this summer day.
I have many clip to see from you🔥🌺🌺
Hope you both have a lovely day 🙂
God bless your humble hart🔥

It’s finally here! Enjoy those warm sunny days Arne.
Thank you my friend..And same to you Sir ❤️
Creating 15 grand part 3
Nice. Takes 16.5 ounces of gold to buy the Dow. Last week it was 16.7 ounces to buy the Dow. That means that, priced in GOLD, the Dow was down this week. Even though it made a new high. Making predictions is risky business, especially if they’re about the future. I predict one ounce of gold to buy the Dow.
What does wet/dry gold sponge feel like when rubbed between the fingers?

Afternoon there Buddy! Just an FYI! 55 Gallons of 70% Fuming HNO³ for $2,800.00 DELIVERED. NO HAZ FEES, though May. "Allied Chemical". Might want to check it out? 55 gallons? That might keep you for a month or two? 😅 I'm going to go for it! My Laboratory is in a 30' x 40' building, out in the country. Plenty of room for a 55 gallon drum! Have a great day, Gunny!

That’s a little bit too much for me to store. I get six bottles every six months or so. That suits me fine. I’m just a hobby level refiner. I remember 14 gallon carboys of nitric for about $400 with a $200 deposit for the stainless keg (carboy). But even that would be way too much for my small hobby operation.
@@sreetips I suppose that you are right. I'm nowhere near your level of production. I hate for it to be wasted. They also have great prices on case lots of 2.5 litter bottles. $335.00, I believe it was. No shipping or Haz fees trough May, as a promotion. New customer's get an additional 10% off. Think I'll give them a try. $335.00 for 15 litters is a pretty good price. Thanks Gunny!
Wade
@@sreetips You know, I was looking for vessels that could withstand the centrifugal forces of a centrifuge. Those, "Carboys", sound exactly like what I'm looking for! I figured that instead of waiting for gravity to drop parcipitate, I'd speed things up a bit? Thanks a second time, Gunny! You are truly AWESOME!
Wade
@sreetips hello my friend. Thankyou for the series. Quick question for you. I was down to my brown mud I then dried it out. Put it in my crucible and started to put heart on it sprinkle a little borax. But it never became a molten puddle and just crystalized? For lack of a better word. Any idea what I did wrong?
Sounds like your flame isn’t getting hot enough.
There's 3:24 seconds left to watch video, excellent video, at 9:19 a piece dropped onto the cotton, maybe a gram
Got it
5:45 a big chunk fell to the side
I should have known that those chunks would gain notoriety and be the highlighted topic of the comments section.
