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. Less abrasive and softer rocks or stones .

The crushing system at the Martha Mine open pit consists of a combination of two types of crushers, a jaw crusher and two Stamler feeder breakers. The jaw crusher is capable of crushing material with a strength of over 150 megapascals (MPa). By way of comparison, concrete has a strength of 20-30 MPa. The Stamlers deal with the softer material.

Crushing. As-mined iron ore contains lumps of varying size, the biggest being more than 1 metre (40 inches) across and the smallest about 1 millimetre (0.04 inch). The blast furnace, however, requires lumps between 7 and 25 millimetres, so the ore must be crushed to reduce the maximum particle size. Crushed ore is divided into various fractions by passing it over sieves through which undersized …

The X-Mine partner Comex has built a container-based pilot sorting prototype to be used as a pre-concentration method after ore crushing. The prototype uses X-ray and 3D sensing technologies to detect ore minerals from waste rock particles, and separates them into two fractions (ore and waste) by using pneumatic nozzles.
