Many other methods have been used for minerals beneficiation. Electrostatic separation utilizes the difference in electrical conductivity between the mineral and the gangue. Air tabling relies upon particle density and shape for separation. Other methods exploit characteristics such as color, radioactivity, and heat capacity. The selection and application of the appropriate beneficiation methods are vital to the economic success of every mineral processing venture.
