mineral dressing of metal ores

  • Mineral dressing (= Orebeneficiation)

    Mineral dressing (= Orebeneficiation) The first process most ores undergo after they leave the mine is mineral dressing (processing), also called ore preparation, milling, and ore dressing or ore beneficiation Ore dressing is a process of mechanically separating the grains of ore minerals from the gangue minerals, to produce a concentrate

    So mineral dressing or ore dressing is commonly regarded as processing of raw ores to yield marketable products by such physical means those do not destroy the physical and chemical identity of the ore 12 Economic Justification of Mineral Dressing: 1 To purify and upgrade the ore: It is apparent that many ores minerals do require some prior

    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
