After screening and washing, the gold-loaded activated carbon will be sent to the desorption operation.

FLOWSHEET DEVELOPMENT FOR GOLD OREBODIES

the gold cyanide in competition with activated carbon (preg-robbing). CIP is a more efficient process for slower-leaching gold ores, and has certain other advantages over CIL, such as smaller carbon elution and regeneration circuits.

Cyanide Use in Gold Mining - Earthworks

A sodium cyanide solution is commonly used to leach gold from ore. There are two types of leaching: Heap leaching: In the open, cyanide solution is sprayed over huge heaps of crushed ore spread atop giant collection pads. The cyanide dissolves the gold from the ore into the solution as it trickles through the heap. The pad collects the now metal-impregnated solution which is stripped of gold …
