Gold extraction QueensMineDesignWiki

Although there are various leaching techniques for free-milling ores, the main technique in Australia, North America, and South Africa is agitation cyanide leaching. Gold recovery is then attained through carbon-in-leach (CIL) or carbon-in-pulp (CIP) methods (Brooy, 1994). The figure below from Lima (2007) shows a typical CIL/ CIP process.
