Gold Mining Operation: 10 30 years. The gold mining operation stage represents the productive life of a mine, during which ore is extracted and processed into gold. Processing involves transforming rock and ore into a metallic alloy of substantial purity – known as doré – typically containing between 6090% gold. During its life, a number of factors – such as the price of gold or

A mercurygold amalgam then is formed because gold will dissolve in the mercury while other impurities will not. The mixture of gold and mercury is then heated to a temperature that will vaporize the mercury, leaving behind the gold. This process does not result in gold that is pure, but it does eliminate the bulk of the impurities.

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
