The gold-loaded sulfide minerals are leached by cyanide after chemical pretreatment. The ore is off-white or white with brown spots on the surface. The brown spots are limonite, which is formed by oxidation of pyrite and magnetite. The ore structure is half-moon-shaped,

Gold extraction - Wikipedia

In 1887, John Stewart MacArthur, working in collaboration with brothers Dr Robert and Dr William Forrest for the Tennant Company in Glasgow, Scotland, developed the MacArthur-Forrest Process for the extraction of gold ores. By suspending the crushed ore in a cyanide solution, a separation of up to 96 percent pure gold was achieved. The process was first used on a large scale at the Witwatersrand in
