Gold extraction
Types of ore Gold occurs principally as a native metal, ie, gold itselfSometimes it is alloyed to a greater or lesser extent with silver, which is called electrumNative gold can occur as sizeable nuggets, as finemm which allows pulp to flow through and out of the reactor whilst retaining the carbon in the reactor The gold aurocyanide complex in the aqueous phase is readily adsorbed onto the activated carbon By the time the pulp leaves the last tank in the adsorption cascade the concentration of gold in the aqueous phase is typicallyThe process design of gold leaching and carboninpulp circuits
