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