For a given circuit, an optimal throughput is usually limited by the transport mechanisms in the mill. This is due to the complex rheology of the pulp at high percent solids. A change in ore hardness can alter the particle size distribution, changing the flow conditions in the mill causing it to choke and to start overflowing the grinding media.

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 ...
