Where To Process Mill Gold Ore

Mineral Processing - KCGM

The process of extracting gold from sulphide ore begins when the trucks deliver the ore from the blast site to the ROM (run of mine) pad at the Fimiston Plant. Here the crusher reduces it to chunks of rock about the size of a fist. The ore is then ground into very fine particles less than one-fifth of one millimetre in diameter in large rotating SAG (Semi Autogenous Grinding) and Ball Mills
