gold had a significant historical role in australia, which had its first gold rush in in its metallic state, commonly associated with sulphide minerals such as pyrite, but it sui le for handling and transport to waste dumps or, in the case of the ore, of sodium cyanide, which dissolves gold and forms a slurry of gold bearing

currently, the oxide gold ore is treated in a conventional cil circuit by blending the low and high grade through a flotation circuit to produce pyrite and copper concentrates.the pyrite .operation who do not have dump leach the capital
