### Grinding Circuit - an overview ScienceDirect Topics

A flow sheet of a typical iron ore crushing and grinding circuit is shown in Figure 1.2.2 (based on Ref. [4]). This type of flow sheet is usually followed when the crude ore contains below 30% iron. The number of steps involved in crushing and grinding depends on various factors such as the hardness of the ore and the level of impurities present [5]. Figure 1.2.2. Flow sheet of typical iron ...
