Why Do We Need Comminution In Mineral Processing?

Crushing is the first operation of size reduction, while grinding comes after. Some processes, such as froth flotation and leaching processes, require a maximum particle area because maximizing the surface of solid in contact with the liquid or gas phase around enhances reaction, dissolution, catalytic effects, etc.

CPE: Lesson 13. Principle of Size Reduction

Reduction ratios depend on the specific type of equipment. As a general rule, the coarser the reduction, the smaller the ratio. For example, coarse crushers have size reduction ratios of below 8:1, while fine grinders may present ratios as high as 100:1.

Introduction to Mineral Processing or Beneficiation

This process of size reduction is called comminution. The crushing and grinding process will produce a range of particles with varying degrees of liberation (Figure 2). Any particles that exceed a target size required for physical separation or chemical extraction are returned to the crushing or the grinding circuit.
