Crushing and grinding of the ore is generally divided into several stages:

Before sorting Crushing and grinding of the ore, the preparatory work is the crushing and grinding of ore,while a prerequisite of the beneficiation is that useful minerals in ore reached single separation. The granularity of useful minerals existing in the monomer is small, sometimes the ore pulverized to less than 0.074 mm, and even smaller, in order to separate.

During the  Crushing and grinding of the ore several stage often used the Mineral processing equipment, crushers, screening equipment, grinding mill machines, belt conveyors and so on.
