Gold mining - Wikipedia

In placer mines, the gold is recovered by gravity separation. For hard rock mining, other methods are usually used. Cyanide extraction of gold may be used in areas where fine gold-bearing rocks are found. Sodium cyanide solution is mixed with finely ground rock that is proven to contain gold or silver, and is then separated from the ground rock as gold cyanide or silver cyanide solution. Zincis added to precipitate out residual …

Gold extraction - QueensMineDesignWiki

Gold bearing ores that include base-metal mineralization, particularly copper, are classified as complex ores. These ores will often consume cyanide and create issues in CIP and elution. Preg-robbing carbon is defined as the phenomenon whereby the gold cyanide complex is removed from solution by constituents of the ore (Rees & van Deventer, 2000).
