gold extraction plants. In the carbon-in-pulp process adsorption occurs after the leaching cascade section of the plant, and in the carbon-in-leach process leaching and adsorption occur simultaneously. In both processes the activated carbon is moved from one tank to another in countercurrent with the ore pulp until the recovery

Summary Of Gold Cyanidation Methods

Summary Of Gold Cyanidation Methods

The carbon in pulp method can also be called all-sliming cyanidation. It is a method in which activated carbon is put into cyanidation pulp to adsorb the dissolved gold onto the activated carbon, and then the gold is extracted from the activated carbon. The carbon in leaching method is developed on the basis of the carbon in pulp method.

May 01, 2011· Gold extraction per stage was ∼70% for Tests 1 and 2, but dropped to ∼60% in Test 3, which resulted in an increase in the predicted soluble losses from the last stage, from 0.003 mg/L to 0.019 mg/L. Intuitively, one might predict that the optimum pulp density is 50%, based on these results, but as shown in the next section, a more detailed ...

The process is known as carbon-in-columns (CIC). For mill, agitated-tank leaching operations, gold is extracted directly from the leached pulp in either a carbon-in-leach (CIL), or a carbon-in-pulp (CIP) plant. In both these cases, the coarse granules of activated carbon are mechanically mixed with the pulp in an adsorption tank, and gold-
