Crushing is accomplished by compression of the ore against rigid surfaces or by impact against surfaces in a rigidly constrained motion path. Crushing is the first mechanical stage in the process of comminution. Stages of crushing: Primary crushing → Run-of-mine ore (ROM) reduced to 10-20 cm (4"-8"), ( " = inch = 2.54 cm)

Mine operators extract minerals from underground mines, surface mines and quarries using machinery and explosives. Some extraction processes, such as stone quarries, may use large quantities of water. After extraction, many types of raw minerals are then subject to processes such as crushing, milling, washing and chemical treatments.

The process of ore formation is called ore genesis. Ore Preparation. It takes multiple steps to extract the “important” element from the ore: First, the ore must be separated from unwanted rocks. Then, the minerals need to be separated out of the ore; Since most minerals are not pure metals, further separation methods are required.

Most rock deposits contain metals or minerals, but when the concentration of valuable minerals or metals is too low to justify mining, it is considered a waste or gangue material. Within an ore body, valuable minerals are surrounded by gangue and it is the primary function of mineral processing , to liberate and concentrate those valuable minerals.
