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.1. Changes in liner lifter design to maximize throughput while maintaining acceptable wear levels. 2. Changes in ball size to maximize particle breakage without producing exceptionally high impact forces. 3. Changes in grate and pan lifter designs to decrease internal mill recycle and increase throughput.
