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 ...

A special development is the autogenous or semiautogenous mill. Autogenous mills operate without grinding bodies; instead, the coarser part of the ore simply grinds itself and the smaller fractions. To semiautogenous mills (which have become widespread), 5 to 10 percent grinding bodies (usually metal spheres) are added.
