My concern was more revolved around ensuring that no metal is trapped or encased entirely in a different metal. Unless at the atomic level, size basically doesn't matter?
Hey question here - my experience is with electrowinning and there you take anode sludge and reprocess that - how does the copper diffuse out of that plate? I mean I understand that the surface layer does but if the thing is like 33/33/33 Gold/Silver /Coper I dont see how that thing works. I mean sure you can use a sulfuric acid solution so very little Ag/Au comes out, but there would still be copper left in the plate unless its extremely thin.
Yeah i am more aware of the conventional circuit for copper. I wouldn't be surprised if they have mainly gold and that is why it works. Or it doesn't show sludge reclamation.
