We don't really deal with gold refining here at SMF. While we do deal a lot in escrap, refining a different ballgame.
Its far more dangerous than anything involved in scrapping metal.
There's so many unknowns and it can go bad very quickly and without you even knowing that its already gone bad.. (The guy who did refining in his garage, using HCL acid, and noticed after 3 days that his $18,000 Saab was developing rust spots in weird places...)
I did intend to gold refine, I tried, and had two close calls involving safety, never got any Gold at all.. Now am the owner of 3 gallons of a bright green highly acid liquid..
So, refinings a bit of a 'No No' here. We don't discuss it past recommending not to do it.
If you want Gold, easy, sell escrap and use that money to buy Gold. Its 100% Gold, in a ingot, and sellable.
Golds all the same really, except the stuff that people refine, since nmobodys going to buy it without a expensive assay. And in getting (if one does) gold, people miss getting any of the other metals, Copper/Silver/Tin/Lead/Platinum/Pladium etc etc.
A good Gold refiner (commercial) makes their money from the 'scrapmetals' in escrap, Copper/Tin/Bismuth/Lead etc.
You get the Gold and PM's back afterwards.
Same with selling escrap, you get it, but in ca$h, minus a few obvious overheads maybe.
If you want some real escrap Gold you got yourself, try 'Patnors method'. Its basically collecting normal IC chips, cleaning the legs off and incinerating the Chips to burn the plastic coating off, then Gold panning out the Gold wires from the carbon dust/Copper legs/silicon die.
Since the wires are pretty much clean, you can melt them down into a chunk, still unsellable, but something you did yourself.
But, collect your escrap, clean it down roughly to make it take up less space, sell your plastic and wire and Aluminium and Copper and Steel cases, sort and in time clean it down again to get it to sellable condition, and sell it in bulk to a buyer from here.
Theres a few to choose from and they can help you get the best $$ for the most effective work/time value.
Good luck and stay safe/e
