The ore lumps from the mines have the lump size of 10 - 100 cm while the individual minerals have grain sizes below 0.1 mm. Hence, the first step in any ore dressing plant is to aim at liberation by size reduction or comminution. Comminution of any ore is carried out in several stages using different crushing equipments.

Predicting the overall specific energy requirement of
Given the energy consumption distribution of ore crushing and grinding [Morrell, 2004, 2008, and 2009], the particle size of the crushed final product should be reduced as much as possible in the production process. The comminution probability of ore in various crushing equipment is about 50% ∼ [Duan, 2012].
