Grinding Circuit an overview ScienceDirect Topics

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.

Evaluation of grinding circuits for iron ore SciELO

Not only does grinding have a direct impact on iron ore recovery, it also significantly impacts costs. The particles can be broken by compression, friction or impact. Wills (2007) explains that when the particle is broken by compression, the product is coarser than when the breakage happens by friction. The bigger the particle, the more the energy required for rupture and the lower the total energy of the mass unit.
