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, 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?

[@phishinca]

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.

[@MuawiyahAlrawahi]

Why tap water is Ok with sliver chloride but you use distilled water wit gold?

[@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.

[@ng-ht1vx]

A question that I have is why didn't you melt all the nonmagnetic into a bar, and electrowin the copper away? It would save a lot of nitric.

[@sreetips]

Sorry, I’m not familiar with that process.

[@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.

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!!!

[@sreetips]

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.

[@RoeMantic]

Sweet here we go!!!

[@pekkarousu3616]

Why not crush the material into powder? It should be easier/faster to dissolve other metals than gold and using less acid?

[@TheRealWeirdoC]

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. :)

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.

[@sreetips]

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.

[@arte47]

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.

"To test whether a solution is containing silver, you only need add chloride . Common table salt, which is sodium chloride, will do. If silver ions are present the chloride will combine with the silver and create a white, cloudy appearance."

I did find a lot about gold/copper alloys and I do wonder how much copper instead of lead is in those blue colored solutions.

Gold also has a melting point 3 times higher than lead so you could just melt it off?

[@Eveseptir]

And I'm no chemist but I'm guessing the deposit is lead chloride?

[@sreetips]

As the metal heated, the lead would melt, flow over the entire piece and create a thin coating of lead solder that’s nearly impossible to remove. Leads not so bad. Easily removed with a little sulfuric acid. But most soft solder contains tin. Tin reacts with nitric acid to form metastatic acid or tin paste. Tin paste is the consistency of Elmers Glue. It will ruin a refiners day because it clogs the filter and makes filtering nearly impossible. Boiling in HCl then scraping off the solder is the easier softer way.
