Mineral processing - Wikipedia
Mineral processing can involve four general types of unit operation: 1) Comminution – particle size reduction; 2) Sizing – separation of particle sizes by screening or classification; 3) Concentration by taking advantage of physical and surface chemical properties; and 4) Dewatering – solid/liquid separation. In all of these processes ...
