Gold in cable ends and connectors?

gold from the cyanide? The only way to gold plate copper or brass is to first plate the surface with nickel. For allumnum they first plate with copper then nickel and then a final layer of gold. It seems to me cyanide would instantly disolve only the gold in liquid form. Then a little murcury would seperate the gold out of the cyanide and heat ...

Gents for fast gold recover from using eco goldex E, use electrowinning. Its very fast. Your gold will not plate pure, but will have silver, copper and other metals. Then you can refine by cupelling with pure lead or AR. Cupels cost about the same as you would spend in AR per gram. Good luck.

" Help ! Have a deplating set up but cant get good yeild"

It didn't seem like the the gold leaching effect was so good as it only dissolved a minor part of the gold in the ore. Enough to be worthwhile to recover but the majority went along with the copper concentrate to the smelter. For ram memory sticks, most of the gold is contained in the thin bond wires embedded in the plastic capsule.

Understanding Gold Processing Techniques

Cyanide leaching is a method that has transformed the gold mining industry with its effectiveness and efficiency. The process involves a chemical reaction between cyanide and the minute particles of gold found within ore, forming a solubilized gold-cyanide solution. From this solution, gold is later recovered, often by carbon adsorption.
