In recent years the use of cyanide in gold mining has become the dominant means by which gold is extracted from a body of ore. The mercury amalgamation process had previously been used but recovered only about 60 per cent of an ore body's gold. In contrast, leaching finely ground ore with cyanide can recover up to 97 per cent of the ore body's gold. The process involves: Removal of all
