On the other hand, the average size of the cassiterite and monazite grains was 66 µm. Therefore, after grinding, one part of the ore remained unliberated. The analysis of cassiterite liberation by grade ranges is shown in Figure 10. A significant amount of cassiterite was found in mixed particles, with % of it being liberated.

1. Introduction. The term chemical additives or grinding aids (GAs) refers to any substance which results in increased grinding efficiency and reduction in power consumption when added to the mill charge (amounts not exceeding wt.% of the feed) during grinding [1], [2], [3].The use of grinding aids to increase mill throughput is quite common in the cement industry [2], [4], [5].
