The plant flow sheet incorporates two SAG mills and a ball milling circuit, cyanide leaching and a carbon in pulp (CIP) plant. Loaded carbon is transported to the central Elution Circuit at 1 Plant. The D1 Gold Plant was commissioned in 1972 as a three stage crushing, two stage milling, filtration and zinc precipitation operation.
BrainWave is ideally suited to stabilize the operation of SAG mills. Effective grinding in a SAG mill depends largely on how it is loaded. A mill containing too much material does not allow for adequate movement of the ore and balls. A mill that does not contain enough material does not take advantage of the autogenous grinding mechanism.
