Project Design of Gold Refinery Plant (Gold-loaded Carbon Treatment)

1.Smelting Process

Adopting exclusive production technology which is proved to be effective by Zijin Mining Group: gold-loaded carbon non cyanide electrodeposition of high temperature and high pressure, coarse gold slime pyro-hydro purifying method, degold carbon pickling-pyrogenic combined regenerative method. There are four production systems according to the above-mentioned process: analytical electrodeposition, refining, regeneration of activated carbon and waste-water treatment. Deal with the waste gas (acid mist) and waste-water.

2.Smelting Process Flow
