    Dec 26, 2015In 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.

    The grinding is usually done with hard ore pieces or hard steel balls, sometimes both. The product of crushing and grinding is a water–particle pulp, comprising ∼35% solids. Flotation is done immediately after grinding—in fact, some flotation reagents are added to the grinding mills to ensure good mixing and a lengthy conditioning period.

    Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on run-of-mine ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition.
