Gold extraction - QueensMineDesignWiki

The gold is not sufficiently liberated as is the case with placer ores, and therefore crushing and grinding is required to allow the cyanide to access gold components. Permeability is the major indicator of how much communition is required prior to leaching. Although there are various leaching techniques for free-milling ores, the main technique in Australia, North America, and South Africa is agitation cyanide leaching.
