How Gold Is Mined

Processing gold involves transforming rock and ore into a metallic alloy of substantial purity – known as doré – typically containing between 60 90% gold. During its life, a number of factors – such as the price of gold or input costs – will affect which areas of an ore body are deemed profitable economic to mine.
