These are: Comminution (crushing and grinding). Beneficiation (separation and concentration). Smelting and refining. Ball mills are employed in the comminution stage as grinding machines ( size reduction ). The purpose of grinders in the mining industry is to reduce the feed material size in order to liberate the minerals from the barren rock.
