Gold Cyanidation Process Mineral Processing & Metallurgy

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. The ore must be ground to a specific size before it can be treated. But

The use of cyanide in gold mining The Violence of

The mercury amalgamation process had previously been used but recovered only about 60 per cent of an ore body’s gold. In contrast, leaching finely ground ore with cyanide can recover up to 97 per cent of the ore body’s gold. The process involves: Removal of all topsoil from the area to be mined.

Gold/Silver Heap Leaching and Management Practices That

In addi- tion, if cyanide is used during agglomeration, the leaching process is initi- ated before the ore is stacked on the pad and may reduce leach cycle time and increase metal recovery. Agglomeration effectively promotes good percolation characteristics in low-grade resources, particularly tailings, that otherwise could not be heap-leached.
