Gold extraction - QueensMineDesignWiki

2019-6-28  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).
