Grinding is the process of first grinding a material into a particle size (such as a) and then specifying a particle size (such as b) that was over-grinded. Accordingly, the particle size between a and b was the required particle size. The grinding technical efficiency can be used to evaluate the efficiency of the required granularity [ 1 ].

Crushing in Mineral Processing

Mar 19, 2017 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.

How to make a thin section

Warning: Most sections fail at this stage because you are grinding too fast! Remember, any time the grinder makes noise against a slide, you are removing rock. You often don't have to advance the wheel at all to just grind a small thickness away. If your section comes out with the minerals all cracked: you were grinding too fast.
