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 0.25 wt.% of the feed) during grinding [1], [2], [3].The use of grinding aids to increase mill throughput is quite …
