Refining gold from ore or concentrates is done during the smelting process.During this process, flux is used to dissolve contaminates such as metal oxides from the gold.The flux is added to a crucible with the gold that is then melted in a furnace.You can make flux for gold refining.
Gold refining techniques sciencing.Another large-scale gold refining technique, the wohlwill process refines gold to 99.999 purity the highest purity possible.Developed by emil wohlwill in 1987, this electrochemical process uses a 95 pure gold bar as an anode and small sheets of pure, 24-karat gold as the cathode.
When i use this refining method, i regard the purity of the gold as 22kt, and i alloy it accordingly down to 18kt or 14kt.This gives me a safety margin so the gold is a slightly higher purity than i stamp it.Safety disclaimers notwithstanding, this process uses nitric acid at 70 concentration, and caution must be used.
Gold processing - gold processing - mining and concentrating the nature of the ore deposit determines the mining and mineral processing techniques applied.Oxide ore deposits are frequently of such low grade e., 3 to 10 parts per million that extensive mineral processing cannot economically be justified.In this case they are merely shattered by explosives and then piled into heaps for.
