1. Introduction. Comminution of the ore can take up to 3050% of the total operating costs of mining (Aldrich, 2013, Jeswiet and Szekeres, 2016).The most energy intensive process in the comminution is grinding, for which the operation cost increases with the fineness of the product (Wang and Forssberg, 2007, Jeswiet and Szekeres, 2016).Generally wet grinding is favoured over dry grinding ...

The first step of physical beneficiation is crushing and grinding the iron ore to its liberation size, the maximum size where individual particles of gangue are separated from the iron minerals. A flow sheet of a typical iron ore crushing and grinding circuit is shown in Figure (based on Ref. [4]).This type of flow sheet is usually followed when the crude ore contains below 30% iron.
