Mill throughput is a key driver for maintaining profitability at Mt Keith because of the low head grade (~0.5% Ni) and inherently low nickel recoveries due to the mineralogical makeup of the ore. The Nickel West Mt Keith Concentrator (NMK) has 2 parallel grinding modules consisting of one SAG Mill and one BALL Mill per module.

The performance of ball mills is very sensitive to the volumetric mill filling which influences grinding media wear rates, throughput, power draw, and product grind size. A pilot plant investigation with an overflow mill discharge has been conducted. For a given throughput, it seems that the pool size has a major influence on the product grind.
