2013-3-7 South African gold mines are deep level mines reaching depths of over three kilometres. Miners go underground in shaft cages and then walk or take trains to the work face. The ore undergoes a series of crushing and milling steps to reduce its size for further processing. Gold is leached from the slurry by means of dilute cyanide solution. Gold has a high affinity for cyanide solution. The
