The basic extraction of metals from ores has the following steps. 1. Grinding and Crushing. The bigger chunks of the ore extracted are crushed and ground in ball mills and crushers. It helps to increase the surface area of the chunks for better chemical actions later. In technical terms, it is called pulverisation. 2.

This section looks at methods to get very large rocks crushed and ground until it is as fine as powder. The first concept that needs to come across here is that minerals are inside rocks and by crushing rocks, the minerals are exposed at the surface of the rock fragment. Only then can chemicals be used to extract the mineral.

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.

Silicon does not occur naturally in pure form, but only in its compounds. After oxygen, silicon is the second most represented element in the Earth''s crust. Silicon is in 26 to 28 % of the Earth''s crust, according to the latest available data. In seawater its concentration is relatively low, only 3 mg Si/l (Meija et al., 2015).
