Cyanide can be used to extract gold, either in a controlled mill environment, or more crudely on rock piles in the open. Cyanide "vat leaching" mixes finely crushed ore with a cyanide salt in water. The cyanide binds to the gold ions, and makes them soluble in water, thereby allowing separation from the rock. This process usually takes place inside a mill or other mining facility. Mine Tailings. READ .
A gold processing circuit [image 145711] The major advantage of Carbon in Pulp is not the reduction in the use of zinc dust but rather the impact on the dewatering requirements. Using carbon allows the gold to be recovered on coarse pellets (16 mesh) of activated carbon. Activated carbon is made from coconut shells or peach pits to ensure the material is hard and doesn't abrade during contact with the .
The ball mill has an effective grinding length of 36' with an internal diameter of 26' and 14 MW of installed power (2 x 7,000 kW twin drive motors) and is in close circuit with the cyclone cluster. The milling circuit is operated at a capacity of 1,450 tph. The CIL circuit consists of two trains of eight tanks in series fed from a common leach tank. The loaded carbon passes into a 15 tonne acid wash column. The gold is .
