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.

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.

[@jowens1126]

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.

[@drcurioustube]

"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.

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.

@@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.

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]

I don’t know anything about cupellation. None of the professional refiners that I learned from use it.

[@TheRealWeirdoC]

@@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 KZbin. Just throwing it out there for consideration in case you were feeling adventurous. :)

[@KiwiKoNZ]

Love it Sreetips! 😎👍✨

[@Armyman365]

If the nitric doesn’t dissolve the gold but does the base metals. How does the acid access the base metals?

[@sreetips]

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.

[@michschep7601]

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.....

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?

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.

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.

Nano particles of gold are just a few microns. They are so small that the gold will suspend in the liquid, giving off vibrant colors from pink through blue and purple. Quite beautiful to look at. But a pain for the refiner. They pass right through a filter paper.

[@sreetips]

If you dissolve gold in acid then it is no longer in metallic form. It becomes a compound of gold called gold chloride or chloroauric acid.

[@jasonjack5915]

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!
