MILESTONES IN THE IMPROVEMENT OF …
efficiency improvements contributed to this downward trend in the nickel recoveries. The loss in nickel recovery was further affected by the fact that the smelting capacity required high mass pull feed input at an optimal concentrate grade, whilst at the same time the ROM ore nickel grade was declining as shown in figure 2 below.

Processing of low-grade ultramafic nickel ores: A critical review
Due to the relative ease of mining and processing, the high-grade mafic Ni sulphide ores have been depleted (Fig. 3) and processing the Ni-bearing laterite ore processing is expensive and challenging (Bobicki et al., 2015, Bobicki et al., 2012). Therefore, low-grade ultramafic sulphide ores represent an attractive Ni resource.

Implementation of the new process at Mt Keith has raised nickel recovery by 10%. In turn, nickel production has increased by over 6000 t.p.a. and the net present value (NPV) of the operation has increased by over A$300 m. These outcomes illustrate the large commercial benefits that can be gained by understanding particle size effects in flotation.
