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.
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.
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!

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.
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!!!
"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.
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.
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.
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
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.
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.....
@@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.
I was skeptical about how much dirt you got out of the first filtration. I was baffled when you did the 2nd filtration until you lifted the beaker to show the gold foils. I noticed a bit of purplish colored mud at the bottom of the beaker. I bet you have more gold than you think in that filtration paper.
Do you mean gold plated...? Filled by definition means to insert or block a cavity... This “filled” terminology is completely new to me and I’m in the jewelry business
Gold filled is a thick layer of karat gold bonded to brass. Gold plated is a thin layer of gold, just a few microns thick (a micron is one millionth of a meter). Gold filled can be identified by its mark; 1/20 12k GF is typical. You can expect about 2.5g of pure gold from 100g of 1/20 12k gold filled material.
@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
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.
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
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
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.
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.
I forgot to add into my previous comment, I only save converting to silver chloride in "emergency" situations. Like a couple days ago I tried putting diesel exaust fluid in silver nitrate to denox, which is something I never do(I never really have excess nitric in my solutions) but I'm working in a massive batch of tungsten/silver scrap. When I added 50-100 ml it created a precipitate that looked like frost, so I filtered put it in 5 gallon bucket and and stuck copper in but it kept forming a hard crusty layer of silver on all pieces of copper! So I had to convert to silver chloride which I hate doing but is a necessary evil! So I'm not sure why but diesel exaust fluid will form a passive layer on copper. My solution was not to concentrated as I had been precipitating double the amount of silver out of the same volume if solution for the past month!
Interesting. Isn’t diesel exhaust fluid urea? I used to put urea in my silver solutions to rid excess nitric until Butcher on GRF pointed out that it doesn’t work.
@@sreetips yes it is urea, I'm not sure why but it happened, I had tried it in a gold solution and it created a reaction red fumes but it didnt have any negative effect. I wanted to try it as I have it on hand because I drive a diesel truck. It didnt rid excess nitric and my experience created a mess.
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.
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 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?
This may be a stupid question, but here goes: Why are you gingerly and carefully handle that giant beker when you filter? Use a glass ladle ... ladle the liquid into the filter. Or a turkey baster...
