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 1.2.2 (based on Ref. [4]).This type of flow sheet is usually followed when the crude ore contains below 30% iron.

Jan 24, 2012 Graphite Graphite is a dark gray to black mineral with a metallic luster, it has relatively low hardness(0.5-1 in Mohs). However, because of graphite's often occurrence as flakes and the covalent bonds strength within the sheet-like graphene, it is very hard to grind graphite to fine particle size. For sizes above 100 microns, most hammer
