Here I present an Process EXAMPLE of Gold Extraction Cyanide in which the cyanidation feed consists of a pyrite concentrate floated after the selective flotation of a coppergold concentrate. The pyrite concentrate is reground to 90% minus 325 mesh and aerated in a highlime solution prior to cyanidation. It contains 99% sulphides of which 10 to 20 percent is pyrrhotite and to % ...
The major drawback of industrial mining is the damage mining operations cause to the environment. Removal of large areas of topsoil can destroy habitats, and the chemicals used in mining operations can leach into the groundwater and pollute the area.
Vat leaching is carried out in vats ranging in capacity from 30 to 1200 tons. Sand for leaching is separated from slime in cones, V boxes, classifiers, and in collecting vats filled by distributors—the overflow in each case being slime or finer portion of the ore. As a rule, leaching is a simple process, involving a vat of wellmixed neutralized sand, ample contact with strong and weak ...
