The application of verticalrollermills (VRM's) for ore grinding is part of the second strategy. The grinding parts of a Loesche mill ( Fig. 1) are a rotating table (1) with a horizontal grinding track and rollers (2), which are pressed onto the table by lever arms and a hydro pneumatic spring system.

The Karara Mine concentrator commenced operation in November 2012 to produce highgrade magnetite concentrate. The circuit consists of three stages of comminution plus magnetic separation at each stage for early gangue rejection. HighPressure Grinding Rolls (HPGRs) are used for fine crushing, followed by ball mills and TowerMills in secondary and fine grinding duties respectively.

In Fig. 1 C, grinding iron ore only produced the finest fraction, followed by the 25 % quartz and 75 % iron ore ratio, equal quantity of the two ore samples, and only quartz material. The 75 % quartz and 25 % iron ratio yielded coarser fractions than quartz only in the range of 150300 µm. It is evidently observed that the addition of quartz mineral with increasing percentage tend to reduce ...

The fine ore grinding section will consist of two parallel streams, each comprising two stages of mills. It will incorporate a lowintensity magnetic separation (LIMS) unit at the end of each milling stage. The mill feed will then undergo flotation in a reverse flotation unit to reduce silica in the final concentrate.

Karara mine had shifted the grinding workload from the primary ball mill circuit to TowerMill circuit by bypassing the scalping screen in between these two circuits to cope with the increase in the throughput. These actions had led to a coarser TowerMill circuit feed and higher mass flow rate that resulted in a coarser circuit product.
