Revisiting Sepro’s Mineral Processing 101 paper, it was written as a review of the fundamentals of mineral processing. The first principle discussed is heterogeneity, which is about taking a relatively homogenous ore and breaking it into small enough pieces that there are differences amongst the particles.

cannot collect the wanted components only. The second objective of comminution in mineral processing is to adjust the size of mineral particles to adapt to the optimum size for the successive separation processes. Screens and classifiers are used to adjust the particles within prescribed and closer size range.

Comminution in the mineral processing plant takes place in a sequence of crushing and grinding processes. Crushing reduces the particle size of run-of-mine ore to such a level that grinding mill can further grind it until the mineral and gangue is substantially produced as separate particles.

The first comminution stage in a mineral processing plant is crushing, which reduces the size of particles from up to 1 m down to 0.5 cm (depending on the type of milling circuit). Crushing is typically a dry process that makes use of Gyratory, Jaw, and Cone crushers (Napier-Munn et al., 1996), which predominantly make use of impact mechanism.

In mineral processing or metallurgy, the first stage of comminution is crushing. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface. Less abrasive and softer rocks or stones are crushed by impact and shear but also compressive mechanisms.
