nickel ore gravity concentration plant - thgroup.co.za

Nickel Ore Gravity Concentration Plant. Gravity concentration is a process to concentrate the mineral of interest by the difference of specific gravity of nickel and gangue minerals. Often gravity separation methods are confused with size classification because large particles of light minerals can behave like a small particle of a heavy mineral.
