Mineral dressing (= Orebeneficiation)

2009-5-16  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
