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.

Crushing Technology : Material Size Reduction Methods
Material trapped between a solid plate and a rotating roll is shorn by its contact with the teeth on the roll. Often the sheer crushing is combined with other crushing methods, such as compression, attrition, and impact, for mineral size reduction. For example, single roll crushers employ shear together with impact and compression.

importance of ore crushing in mineral process
Crushing is an important step in the complex process of mineral processing (Fig. 1). In open pit mines, rock chunks with edge lengths of 2 m have to be processed. In underground mines, the biggest chunk sizes are about 0.5 m. Crushers have the task of reducing the ore rock to particle sizes in the millimetre range for subsequent grinding.
