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.
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.
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
@@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!
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.
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!!!
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.
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
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.
"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.
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 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.
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
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.
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’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.
Did you serve on an Adam's Class Destroyer during Operation Desert Shield? Thank you for your Service. I was working with the USS Henry B Wilson, DDG-7.
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
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?
@steetips absolutely love this video, length irrelevant, over the past few years studied this process in depth, sourced information and safety precautions, however I seem to find I have a block on identifying all equipment to build a safe environment to conduct this, I've sourced some of the beakers but without knowing the correct name for the different apparatuses and tools I can't find them, would you be so kind to elaborate on your inventory of tools and apparatus, I would greatly appreciate it.
@@sreetips I totally agree, I did a small version of this few years back and immediately killed the reaction when I noticed the fumes, ive built a fume hood since with a ventilation chimney just over 3m high getting those fumes up and away when I do it again, I was referring to different types of flasks and drip feeders you were using, what are their technical names please
I don't get boiling the lead off the bracelet with the acid and scraping it off. Lead has a melting point of 622 degrees F. Couldn't you just melt it off?
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.
41:37 Love your videos, buying equipment to learn. So, what is called or how do I create a similar Vacuum rubber cork/top for a flask like this. I do have 1000ml vacuum filtration flasks, so I suppose I only need the so called rubber cork & boro adapter and hose with boro suction pipe. Sorry if I sound like and Idiot! btw, I watched the video where you did not have a long enough stem past the vacuum. That was fun:}
@@sreetips 35:27 I added the wrong time stamp earlier. My question is about the cap on the Flask and the adapters used to have a similar system. Thanks
@@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.
Jrod, I’m not actually a trained chemist. I took a chemistry class once, in high school, fifty years ago. I got a D. You don’t have to be a chemist in order to refine precious metals. But it helps much if you are a chemist.
Whats the cost efectiveness of doing this i feel like with the amount of chemicals used you would only be making money on this by doing very large batches of gold recovery
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.
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.
This is oddly cathartic for me. Seems like a hobby I'd love to get into (that could be combined with another hobby like making metal objects). @Sreetips, what would you say the investment, or even just a list of items, would be to have a legit setup for smelting/refining/smithing?
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.
This process won’t work on “plated” gold. This is for gold filled material only. Gold plated material must be run through a sulfuric acid stripping cell. Please see my video on how to build and operate one.
Is it possible to selectively dissolve just the gold and leave the base metals, maybe with hcl acid and bleach or something that only attacks the gold?
Sorry, read it wrong. Selectively dissolving just the gold don’t work. Best to dissolve the base metals out first. Then refine the left over gold pieces.
With that amount of base metal, especially with all that lead and tin to deal with, this may have been a good opportunity to try your hand at cupellation.
@@sreetips Ancient technique, but still used today, especially for fire assays. Dan Hurd and MBMMLLC both have good videos showing the process if you just want to see what's involved. Basically, it uses lead and a selectively-absorbent melting dish to part out the base metals, leaving gold, silver, and PGMs consolidated in a bead. All of the waste produced is in the form of a dry solid "litharge cake", and it eliminates the need for such a massive amount of nitric acid for dealing with the base metals. Certainly can't fault anyone for just sticking to what they know works, though, and you are (at least from what I can tell) the most experienced and knowledgeable refiner on TH-cam. Just throwing it out there for consideration in case you were feeling adventurous. :)
If i remember right, citric or hydrofluoric acid can be used to remove lead, makes a water soluble compound that disolves and washes away, leaving gold behind.....
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.
Your videos are just amazing! I really enjoy watching it from start to end even they are pretty long that's something good in this case. You sir are really professional working with chemicals and your final 999 pure metals shows that. Also I would like to let you know I really appreciate the fact you use both imperial and metric system, and also Celsius scale. Please keep making videos. Greetings from Argentina.

Steven.
It has been a bit chief! Love it
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.

All of the waste produced is in the form of a dry solid "litharge cake", and it eliminates the need for such a massive amount of nitric acid for dealing with the base metals.
Certainly can't fault anyone for just sticking to what they know works, though, and you are (at least from what I can tell) the most experienced and knowledgeable refiner on TH-cam. Just throwing it out there for consideration in case you were feeling adventurous. :)
Why not crush the material into powder? It should be easier/faster to dissolve other metals than gold and using less acid?
The precipitate after the HCl reaction is lead (II) chloride
Can you “over dissolve” during the recovery step is there a danger of using too much acid
I’ve seen boiling nitric put small amounts of gold in solution. In that sense I guess the answer would be yes.
BACK AT IT AGAIN!!!! 😩🙏😩🙏😩
If i remember right, citric or hydrofluoric acid can be used to remove lead, makes a water soluble compound that disolves and washes away, leaving gold behind.....
If it has lead and spring steel, would cuppeling it after a chemical process remove it?
I don’t know. I’ve never used cupel
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.
Your videos are just amazing! I really enjoy watching it from start to end even they are pretty long that's something good in this case. You sir are really professional working with chemicals and your final 999 pure metals shows that. Also I would like to let you know I really appreciate the fact you use both imperial and metric system, and also Celsius scale. Please keep making videos. Greetings from Argentina.
