    Crushing In Mineral Processing - 911 Metallurgist

    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.
