Crushing in Mineral Processing
In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock ( geometallurgy ) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.

Crushing is the first mechanical stage in the process of comminution. Stages of crushing: Primary crushing → Run-of-mine ore (ROM) reduced to 10-20 cm (4"-8"), (" = inch = 2.54 cm) Secondary crushing → From 10-20 cm to about 1-2 cm (1/2"-3/8"), Tertiary crushing → From about 1-2 cm to about 0.5 cm or less (<1/4").

Crushing is the first mechanical stage in the process of comminution in which the main objective is the liberation of the valuable minerals from the gangue (Lewis et al, 1976). Crushing is accomplished by compression of the ore against rigidly constrained motion path.
Mineral Comminution and Separation Systems
consist of size reduction (or comminution) by crushing and grinding for the liberation of minerals, separation of mineral particles by va rious principles and a number of operations associated with them. However, most of the processes are basically physical (or mechanical), even if stone effects may play important roles.

Mineral and Mining Engineering: What are the differences ...
Crushing is the initial stage of comminution (the action of reducing a material) in mineral processing. The objective is to achieve the desired size range for the next step, which is grinding. This is achieved by using a combination of heavy duty mechanical crushers, mills ans screens in order to pulverize, classify and recirculate the material.
