Hey Sreetips, dont ever worry about time on your videos. I could sit here for two hours if need be, and still enjoy every minute from beginning to end.
Have been watching different methods and recovery videos for about a year now in addition to reading, learning more and more. Definitely my favorite channel! The long-form videos and explanations of processes are an amazing wealth of knowledge. Hoping to be ready to start refining soon and feel pretty confident that I can maximize my yields using the vital tips added into these. Thanks Sreetips!
Don't worry about the length of the videos. I'm learning and taking notes :) Keep up the great work. I am ready to try my luck with gold and silver recovery.
I know this video is a year old. But I found your channel about two weeks ago, and I’ve been hooked since. I never knew how much work goes into breaking down and purifying gold.. love the content.. keep up the great video’s
This man knows how to disolve your body in a very fun way, and safely use up the remaining acids. Thanks, Sreetips! We obviously love your work, or we wouldn't watch!
See, you fuckin up & know it but now hoping some jokes will save you. You're lucky a certain 3 letter agency keeps him on a short leash in exchange to use his Michael Myers/Walter White psychotic super traumatic background in teaching asshole teens otherwise he'd be extracting your semen through your nose using a chemical reaction involving your own fart.
@@sreetips smart move. Some might find it dull or annoying but most find it important. I never mind a longer video if it is actually teaching me something.
Absolutely. Include the footage. We have a button to skip forward if we don’t find a segment needful. But there is no button to add segments that aren’t included! Never know what little bit may be meaningful to someone. Thanks for what you do Sreetips!
Thank you for your advice about hitting items with the torch it saved me from a mess. I found what i thought to be a set of 2. 14kt g.f . channel 5 pens but turned out to be plastic over aluminum. If i threw that in my aqua regia the aluminum would probably have dropped out my gold. Torching will be a new mandatory step for me( every time) thank you sir.
My collection of GF and GR is growing to the point I am getting worried about the refinement! Thanks for the update on the acid boil to remove the lead. I cut my bracelets, but not full on destroyed them to check for that....back to the cleaning table!!!
Those videos getting better to great is so much I learn from you I can said are better than go to eny school to learn this quimetry art thank you so much
I can only imagine what happened that left all these colourful splashes on the walls of the boiling room. 🤔😂😂😂 Fantastic video, very professional. Thank you
Hi Sreetips. For your next batch please consider to try the eco goldex surface gold stripping and recovery system. It seems so much easy to recover the gold that way for gold filled scrap. No acids, no need to burning anything, It doesn't matter what base metal you have. I'd like to hear your comments on that option and better yet to watch you demonstrate that option.
Hey Sreetips. I LOVE your channel. For those of us who want to get into what you're doing, could you break down all the equipment you use, how much you go through, approximate cost and where to get it? Thanks
I enjoy the length and details! ;) Would it be reasonable to melt down all this stuff into shot? Just like inquarted gold? And dissolve that? It seems like it would save significant time and effort cleaning.
so its safe to assume this scrap gf is roughly 2.5% gold by weight? so if i buy a batch form ebay I can roughly calculate what yield to expect to determine how much i should spend on the batch?
Hey Sreetips, if I had a large amount of absolute junk with gold in amongst it, could i place them 1st in a hot HCl bath, rinse with clean water, then a hot nitric acid bath, then rinse, then lift it with an aqua regis bath, filter, then drop and melt? Would that be a moderately efficient way of obtaining gold from say, various electronic junk?
This is a really bad idea. It will create a large amount of hazardous waste starting at the first step. I would recommend you do a little research at the gold refining forum. There are plenty of posts on how to properly process this type of material.
Love the videos! I’ve leaned a great deal. Thank you. I wander why no one uses a screen material under the filter. Keeping the filter off those holes would make your surface area exponentially larger.
Knowing how pupils are and how some dumdums are handling chemicals, there would probably have been serious/deadly accidents by now, so it makes sense they don't show it in schools :D
question with gold filled, so after hot nitric treatment and filtered foils do you put that old solution right in your stockpot or do you add copper or hydrochloric acid to get silver out filter silver then put it liquid in waste container or do you put it in stockpot?? I’m assuming the only thing you add to your stockpot is after you precipitate the aqua Regia and filter out the gold that old aqua regia goes in your stockpot correct?? Ty for all your help in the past!!!
No silver solutions go in my stock pot - ever. After I remove the silver, either cemented on copper or silver chloride conversion, the waste copper goes into a bucket with copper in it and sits for several days. Then I transfer the copper solution to my waste treatment bucket.
8:20 Im assuming this material is primarily PbCl2, which is very insoluble in solution and would form if the solder was indeed lead based as stated earlier
I’d put it in a container. Soak it in hot tap water. Then add some soap, shake it to loosen dirt. Pour out the dirty liquid and repeat. For the last treatment: rinse with hot tap water until all the soap is off. Dry with a heat gun. Then proceed with incineration and recovery in hot nitric in a fume hood.
"Warranted 14K" usually means solid gold on an old pocket watch case, unless accompanied with a year guarantee designation (e.g.,10,20,25 years). Always good to acid test those. Of course, since you are scrapping the metal, it makes little difference, although it will give a misleading higher percentage result when you do the math, because you have the solid gold in there.
Awesome video that addressed several current questions that I had. BTW, about how much did you pay for all that if you don't mind. I'm still learning what some stuff is worth. Very hit and miss on ROIs so far. Thanks again. I really enjoy your "classes".
@@graymouser1 When you have worked with solder you find there are many different ways of removing it cleanly from alot of surfaces he merely chose what another chemist had done from the book he is using but heating it for 20 mins would get most of it then it would take less acid to deal with the rest or if your thorough enough the amount can be dealt with later in the process.
How do i go about obtaining this amount of scrap, myself? Im getting into gold collecting mainly for wealth safety, but i wanna have fun obtaining the stuff :p
What is your opinion on just melting and pouring GF into shot? I have done this and it basically “inquarts” it. Then rip it in dilute nitric and Black powder was all that remained… I then dissolved it in AR. Saves the roasting/cleaning step. Of course I previously carefully tested and separated steel springs, bands etc. So instead of just the recovery phase it actually becomes the first refining stage potentially saving chems and definitely time.
Deplating gold plated material in a sulfuric acid stripping cell (the only way I know of to do it properly) produces a fine black powdered gold that is heavily contaminated with other metals. I wouldn’t recommend skipping the refining of the black gold powder.
Hello, I wounder if you use once cyanide or like me you find it too dangerous? In this case what do you think about some mixture chemical like ecogoldex.
No experience with ecogoldex I don’t know what it is. My friend the jeweler used to use cyanide. He said the draft blew some of the gas back I into the room he was working in. His tongue and lips immediately began to swell and tingle and he watched a fly drop dead out of mid flight before he could run out to get away from the gas. I’ve never used cyanide or mercury in any of my processes.
Small question (and maybe im just missunderstanding something here) but wouldnt it be possible and more efficient to use gold filled or gold plated stuff to inquart carat gold (because of the high base metal content in there)? You wouldnt need to add as much silver and also the amount of chemicals you would need is lower. Or is there something i dont know about which would make that not possible for some reason?
Gold filled can be used. But it increases the chance of getting lead and tin in with the gold. For this reason I process GF separately. Gold plated is junk metal coated with copper, then plated with a few microns of gold. Definitely don’t want that near our karat gold. I refine silver so it benefits me to use clean sterling silver to inquart the gold.
It is an interesting video. The idea of recovering precious metals is important and can be profitable. It must be said, however, that it is difficult to find so many electronic scraps to be able to extract all this wealth. In many countries it is even illegal. In others, it can be done but you have to buy them and to buy them, the seller calculates how much to ask you based on the average value of extractable precious metals. So, (almost certainly) not convenient. In all cases it is a useful and serious video because it clearly explains the danger of the necessary procedures. Interesting
this guy is amazing...i want him to know he has a big black following... we like his style , like his game, and learn from him..and appreciate him.... and respect him...i like to point it out ...as it helps build bridges.
I'm just curious, are you taking notes in a book or can you do all this by sight, memory, and observing your results? I would love to see a clip of what that notebook looks like. You seem meticulous in you methods.
With the gold contend reduced by inquartation, the nitric can then penetrate to the core of each piece, forming a honeycomb structure as is goes, to successfully remove all the silver and base metals. The process is so effective that the gold is very near three nines after the nitric boils. But the only way to be sure is to refine it with aqua regia.
Hey Sreetips, dont ever worry about time on your videos. I could sit here for two hours if need be, and still enjoy every minute from beginning to end.
CZcamsrs like shorter videos because they get more views per minute of footage that way.
Yes. These videos are filled with good sense, unlike some of the other stuff on CZcams... 😏
👍 agreed
I agree with you. This is just about the most interesting stuff on CZcams.

I could watch hour long videos of this. Its an a.s.m.r. Metal to liquid to powder to metal. I will never get tired of seeing these reactions.
Don't worry about the length of the videos. I'm learning and taking notes :)
Keep up the great work. I am ready to try my luck with gold and silver recovery.
Very happy to have a new video from Sreetips thanks man.

No worries about time on your videos enjoying every minute of it and ready for part 2
Coming tomorrow
You're 5 liter beakers which company can I get them from the one that you're using
As long as you have the data, make the video as long as you can! I love listening to all the science, its strongly calming and im unsure why.
I’ve been tempted to skip footage and shorten it up. But I always reason; you shot it so just go ahead and include it

Harold_V (one of my mentors) used to say, “the three most important things about refining are, incineration, incineration, and incineration”
Yes sir. Wish i could use incineration to recover silver from my 77lbs of used x-ray films. But my neighbors and wife would have a fit ...lol

It seems like it would save significant time and effort cleaning.
With the lead content, could you have heated up the material enough just to melt any lead or glues instead of heating in acid?
Steven.
My all the teachers were just like you.... Finally i became tailor now and stitching dress 😅
Keep it going!
i love you voice and the gold!
Thank you
I actually enjoy the longer 30-45mins videos.
Some folks like the longer videos. Others just want to see the metal.

This is a really bad idea. It will create a large amount of hazardous waste starting at the first step. I would recommend you do a little research at the gold refining forum. There are plenty of posts on how to properly process this type of material.
you can also use Sodium Hydroxide and Hydrogen Peroxide to dissolve the lead on the gold filled parts. That will also remove the Tin as well.
Hi,
What does it mean when you melt gold jewellery down and it all turns black rather than molds together?
Not enough heat. Or, it’s not gold.
Nice ashing furnace. I had been looking into them
That things get hot fast
Could those crystals be lead chloride? Hoke says they’ll form when the acid cools down.
Love the videos! I’ve leaned a great deal. Thank you. I wander why no one uses a screen material under the filter. Keeping the filter off those holes would make your surface area exponentially larger.
Those filters become very weak after they get wet. A screen under the filter would probably cause the filter to fail.
@@sreetips well now that makes good sense. Thanks for the reply.
If high school science class did this I would of paid attention

546th! I can’t stop watching your videos! So many steps to refine precious metals. BUT WELL WORTH IT IN THE END! Roger in Pierre South Dakota
14:20...so what is the yellow vapor thats formed? chlorine gas?
The way that nitric acid just eats the metal away from the inside of the gold is fascinating. Crazy how well that works.
Good work Sir

Hi sreetips; love the videos. What's the best way to clean gf, etc. if we don't have an ultrasonic cleaner? Thanks!

For the last treatment: rinse with hot tap water until all the soap is off. Dry with a heat gun. Then proceed with incineration and recovery in hot nitric in a fume hood.

Hello mr.sreetips , I enjoy your video very much. You are a very good teacher. Just wondering if can do a video for refining ruthenium. Thanks Thien
I can get platinum and palladium. The other four in the platinum group are a complete enigma to me: Rhodium, iridium, ruthenium, osmium.
I dont even do it anymore but that was very refreshing
Awesome video that addressed several current questions that I had. BTW, about how much did you pay for all that if you don't mind. I'm still learning what some stuff is worth. Very hit and miss on ROIs so far. Thanks again. I really enjoy your "classes".
My wife gets most of it at local sales and thrift stores.
in other videos you use sulfuric acid to precipitate lead out of the aqua regia. could you not do the same for that first demonstration?
I was thinking the same.
would it have helped shredding/milling the original material before adding the nitric acid ?
I’ve never tried it
I have a couple question, what do you do with the waste material such as copper or other metals that get separated? Do you also refine them?
No, I throw the copper away
You could have just heated the solder lead solder has a melting point of 700-800F where as gold melts at 1943F
That would remove the bulk of it, but he'd still have to wash it they way he did.

What was the name of the book you referenced in the video, Hopes Finding Precious metals?
Refining Precious Metal Wastes by C.M. Hoke available for free on scribd.com type “hoke” in their search block.

What is your opinion on just melting and pouring GF into shot? I have done this and it basically “inquarts” it. Then rip it in dilute nitric and Black powder was all that remained… I then dissolved it in AR. Saves the roasting/cleaning step. Of course I previously carefully tested and separated steel springs, bands etc. So instead of just the recovery phase it actually becomes the first refining stage potentially saving chems and definitely time.
I’ve done many batches using the technique that I was taught. My opinion, if it works good for you them keep doing it. And that’s what I’ll do.
Why tap water is Ok with sliver chloride but you use distilled water wit gold?
Best to use distilled water. But it cost ten times more than tap water and a pain to haul it in out of my car. So I use tap water when I csn
Hey Sree, would the purification process be necessarily required after you deplate gold plated material?
Deplating gold plated material in a sulfuric acid stripping cell (the only way I know of to do it properly) produces a fine black powdered gold that is heavily contaminated with other metals. I wouldn’t recommend skipping the refining of the black gold powder.

Could you have used a cupel to purify the lead contaminated gold?
I'm just curious, are you taking notes in a book or can you do all this by sight, memory, and observing your results?
I would love to see a clip of what that notebook looks like. You seem meticulous in you methods.
I record weights and yields. But I’ve memorized the process after doing it so many times it becomes second-nature.
If the nitric doesn’t dissolve the gold but does the base metals. How does the acid access the base metals?
With the gold contend reduced by inquartation, the nitric can then penetrate to the core of each piece, forming a honeycomb structure as is goes, to successfully remove all the silver and base metals. The process is so effective that the gold is very near three nines after the nitric boils. But the only way to be sure is to refine it with aqua regia.
