Mineral beneficiation and ore dressing

The crushing process is by the run-of-mine, whereas the ground, i.e. the second step after crushing, is on dry material. Heavy forces such as compression, impact (mainly for crushing) and attrition (mainly for grinding) are responsible for crushing or grinding. Crushing and drying are slightly different, as crushing involves a drying process.

Ore Crushing

The ore crushing process includes four types: ore coarse crushing, ore medium crushing, ore fine crushing, and ore superfine crushing.
