    The Mining Process. 1. Mining open pit and underground. To define the ore from the waste rock samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers. Dump trucks haul the rock to the primary crushers in the open pit or to

    The reagents help us to separate the valuable mineral content from waste rock and iron sulphide particles like pyrite or "fools gold". Air is forced through the slurry creating bubbles which float to the surface and attract and bind to the copper particles. The glossy mineralladen "froth" is then skimmed off the top and dried. The greenish powder that remains once the water content of

  • Extracting Gold HowStuffWorks

    To isolate pure gold mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravellike material then enters rotating drums filled with steel balls. In these drums the ore is ground to a fine slurry or

  • Making the grade understanding exploration results

    COPPER 10% copper would be very highgrade but very often copper occurs with other base and precious metals so I would consider a value of 5% copper to be a rule of thumb threshold for thicknesses of 2 metres and up. The Nevsun Resources Timok Project in Serbia has indicated resources for the Upper Zone estimated to be 1.7 million tonnes averaging 13.5% copper and 10.4 g/t gold
