Therefore, the first part in any ore dressing process will involve the crushing and grinding (which is also known by a common name called "comminution") of the ore to a point where each mineral grain is practically free. Crushing. Comminution • Crushing and grinding are usually carried out in a sequence of operations by which the lump size is reduced step by step. There are 3 stages of

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

Ore-dressing and benefaction are the alternative names for the term concentration of ore. To obtain a pure metal from ore, the method of ore concentration is a very crucial step. For the extraction of metal, it is necessary to separate ore from the gangue particles. Ore found in the earth contains many impurities like sand, grit, rocks etc. which are collectedly known as " Gangue". The
