The comminution circuit comprised a single jaw crusher feeding directly into a single stage SAG mill in closed circuit with one pair of 400 mm Cavex cyclones. The classification design was inflexible and inefficient resulting in a significant amount of liberated pentlandite reporting to the cyclone underflow.

A hammermill is one of several types of crushing machines, including impact crushers, jaw crushers, and cone crushers, that is manufactured for the purpose of processing raw materials to reduce them in size. In the crushing industry, there are two types of forces used to reduce the size of materials: impact forces and compression forces.
