    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, which is dictated by the grade and recovery of the final product To do this, the mineralogy of the ore needs to be considered as this dictates the amount of liberation required and the processes that can occur The smalle
