Crushing in Mineral Processing

2015 12 26 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.
