Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm. Copper ore crushing process. 1.

The iron (Fe) content of such ores ranges from 72% to 35%. The highly friable and fully liberated constituents in ore, such as alumina and silica, generate a large quantity of fines during mechanized mining and crushing. Fine gangue material or iron ore slimes having <45%–55% Fe are discarded as reject during the ore beneficiation process.

The crushing process is by the run-of-mine, whereas the ground, i.e. the second step after crushing, is on dry material. Heavy forces such as compression, impact (mainly for crushing) and attrition (mainly for grinding) are responsible for crushing or grinding. Crushing and drying are slightly different, as crushing involves a drying process.
