Mining and Minerals

2020-2-14 · Gold Recovery GOLD Carbon-in-pulp (CIP) is the sequential leach and adsorption of gold from ore. During the leach, pulp flows through agitated tanks where sodium cyanide and oxygen dissolve the gold into solution. The solution then flows through agitated tanks, where the gold adsorbs onto activated carbon, flowing counter-current to the pulp.

Operations

Ore is treated using a two-stage crushing process, followed by a two-stage grinding circuit that consists of a semi-autogenous grinding mill and a ball mill. Most of the ground ore is fed to a gravity circuit that recovers about two-thirds of the gold, which is then smelted on site to form doré bars.
