The extraction of copper from ore is normally carried out in three major steps. The first step, mineral processing, is to liberate the copper minerals and remove waste constituents—such as alumina, limestone, pyrite, and silica. The second step, involving either smelting or leaching, removes a large proportion of impurity elements.

Mineral and coal processing encompasses unit processes required to size, separate, and process minerals for eventual use. Unit processes include comminution (crushing and grinding), sizing (screening or classifying), separation (physical or chemical), dewatering (thickening, filtration, or drying), and hydrometallurgical or chemical processing.

The first comminution stage in a mineral processing plant is crushing, which reduces the size of particles from up to 1 m down to 0.5 cm (depending on the type of milling circuit). Crushing is typically a dry process that makes use of Gyratory, Jaw, and Cone crushers (Napier-Munn et al., 1996), which predominantly make use of impact …
