They tells no used aqua-regia technology, reagent that disolving Au making directly in reactor. No toxic fumes and etc. They using hydrochloring process in electrolise with using membrane.
@cyrusvariava the electrolysis process seems to be a variation of the Moebius process. first step is removing copper from the bar via a membrane electrolysis cell with dilute sulphuric acid being the clear liquid and copper sulphate being the blue-green one.
second step is aqua regia disolving of anode slime, followed by gold precipitation with ferric sulphate or sodium metabisulphite.
i do not understand the language, i just guessed the above ideas.
the electrolyte may also be a mix of sulphuric and nitric acid, that would explain the greenish colour, because pure copper suplhate is actually blue.
copper does preferentially go into solution when attacked by the electrolyte anions because it is more reactive than silver or gold, the later do not oxydize that easily.
after the copper content of the ingot gets transferred to the copper sheet you see, the leftover slime will contain the more inert silver, gold, platinum and palladium
a russian video with deep south blues slide.... what?

done some further reading, the electrolytic refining is the Fizzer Cell Process

what a waste. All that information and I do not understand a work they are saying. I really like the vioeo too.

i also look for more information.
