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.

First the rock will enter the crushing chamber and drop as far as the angle of the crushing surface will allow it to. The crusher "breaks it and the fine material produced will drop through the gap between the mantle and the liner as it opens. The coarse material that can't fall through will remain to be crushed with the next gyration.
