1. gravity separation or hydraulic washing:
this method is employed when ore is heavier than the gangue associated with it. the powered ore is washed in a current of water.the lightier gangue particles are washed over much larger distances than the heavier ore particles which later settle down. the oxides ores are generally concentrated by this method
