Mineral Grinding Recovery


Mineral processing - Wikipedia

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 stone 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 …
