Refractory Ore Treatment
Rock that contains the least amount of gold is transported directly to Heap Leach pad where it is spread out by front end loaders. It is then treated with lime and cyanide. This dissolves the gold contained in the ore.
Gold bars are unrefined gold bullion bars containing anywhere from 60% to 95% gold. The bars are sent to a refinery for further processing into pure gold. This Gold Bar is the final product of PT Newmont Minahasa Raya.
