Aug 12 2015 The Cyanidation Process or CYANIDE LEACHING is most notably used in the recovery of gold. Safety and environmental concerns are of prime importance in the operation of a cyanidation plant. As we get farther into this type of recovery you will see why. The preparation of the ore for processing is similar to flotation.

Cyanide Use In Gold Mining Earthworks

Cyanide Use In Gold Mining Earthworks

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 and resprayed on the heap until the ore is depleted. Vat or tank leaching The ore is mixed with cyanide solution in large tanks.
