Extracting Gold HowStuffWorks

Removing the gold bearing rock from the ground is just the first step. To isolate pure gold,panies useplex 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 gravel like material then enters rotating drums filled with

Artisanal and Small Scale Gold Mining Without Mercury

The flux acts to decrease the melting temperature and viscosity of non gold minerals in the concentrate so they are more easily separated from the gold during the cooling process. Small amounts of concentrates, usually around 50 to 100 grams, are used in direct smelting. Concentrate and flux are heated in the crucible to the temperature at which gold melts, 1065 degrees Celsius. Miners usually
