As the amount of sulphide material treated increased, gold recovery decreased in response to the refractory nature of the ore. Testwork indicated that a 6% increase in recoverable gold could be obtained by grinding the sulphide material to 80% passing 10μm and leaching the mill product combined with the flotation tails in the existing carbonin leach (CIL) circuit.

Autogenous Mill. Autogenous mill is a type of grinding equipment that crushes material by mutual impact, grinding and peeling effect among material grains. In 1880, cylindrical grinding mill was invented. In 1899, it was used at a gold mine. Since then, it was discovered that autogenous grinding of ore is possible.
