Crushing in Mineral Processing

Dec 26, 2015  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.

25.3 Crushing and milling Mining of mineral resources ...

Once the ore is on the surface, the process of getting the mineral you want out of the rock can start. Once the mineral is separated from the rest of the rock, the mineral needs to be cleaned so that it can be used. This process can be represented by the following flowchart diagram: In this chapter we will look at each of the steps in more detail.
