Ore Processing Waihi Gold

ore is stockpiled at the processing plant, and the process begins by feeding the ore into a hopper with a loader. the ore is conveyed, and lime is added to raise the pH of the ore. following crushing through a jaw crusher the ore is fed into the semi autogenous grinding mill along with water and steel balls.the efficiency of the mill to break ore is a function of both the feed size distribution and the relative hardness of the ore. when the feed size of a sag mill becomes coarser, i.e. increases
