Equipment For Mining Operations | Westpro Machinery

Mineral processing, also known as ore dressing, is the process of separating commercially valuable minerals from their ores. Mineral processing involves four general types of unit operation: Comminution – particle size reduction (i.e. crushing, grinding, etc.) Sizing – separation of particle sizes (i.e. screening, classification etc.)

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.
