$hello \: mate$

Question : State two methods of concentration of ores in which the heavy particles of ores can be separated from the light gangue particles by the gravitational method.

___________________________________________

Answer : Gravity separation process is used for the concentration of haematite. Gravity method is based on the difference between the densities of the ore particle and gangue. It is used for the concentration of denser ores from the water soluble and lighter impurities (gangue). Oxide ores and carbonate ores are concentrated by this method.
