By flowing the powdered ore in a current of water, the lighter rocky impurities can be washed away and the ore particles are left behind. For this, either wilfley table or Hydraulic classifier is used. Generally oxide and carbonate ores are concentrated by this method. i.e. haematite and cerussite. There are two gravity concentration methods.
