There are numerous methods of concentration and the methods are chosen based on the properties of the ore. Hydraulic Washing: This method concentrates the ore by passing it through an upward stream of water whereby all the lighter particles of gangue are separated from the heavier metal ore. This is a type of gravity separation. Magnetic ...
Grinding. Ball Mill or SAG Mill: The crushed ore may then be fed into a grinding mill to reduce the particle size to a powder form. Separation. Flotation or Gravity Separation: The fine lead ore particles are then subjected to a separation process to concentrate the lead content.
