Refractory Gold Technology

Many gold ores and concentrates contain fine grained gold locked within sulphide minerals, such as pyrite andor arsenopyrite, unavailable for recovery by conventional leaching. In Sherritts gold process, the sulphide and arsenide minerals are completely oxidized by pressure oxidation, thereby liberating the gold.

I have scrap gold chains, gold ring, many old cell phones, including sim cards, some computer motherboards I like to process to extract the gold amp silver.
