How Gold Is Mined

The gold mining operation stage represents the productive life of a gold mine, during which ore is extracted and processed into gold. Processing gold involves transforming rock and ore into a metallic alloy of substantial purity – known as dor – typically containing between 60-90% gold. During its life, a number of factors – such as the
