    Mineral processing can involve four general types of unit operation comminution particle size reduction; sizing separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering solid/liquid separation. In all of these processes the most important considerations are the economics of the processes and this is dictated by the grade and recovery of the final product.
