    4/9/2014· It is just not usually viable to mine 0.1 g/t gold. When we will “run out” of each mineral in this chart is based on current reserves and prices. If the gold price doubles, then suddenly it is economic to mine more. 2. This chart is a reminder that something has to give. Either prices are going to have to go up, or new amazing discoveries have to be made to keep prices down. It’s basic

  • Ore Grade Reconciliation Techniques A Review

    The delivery of ore to the Run of Mine (ROM) from multiple sources and the feeding of material to a common ore pass from multiple stopes are issues of significant concern to the reconciliation process. These, inadvertently, could lead to difficulty in tracking material through the mining and milling processes. A consequence on the reconciliation process is the smoothening out of the

  • 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
