ity separation using heavy media. Magnetite is the most widely used material for heavy media because of its higher stability in suspen-sion, higher specific gravity, lower viscosity and easy availability. Worldwide, almost 60 of total coal beneficiation is carried out by heavy media process. In India in 80 cases the heavy media used is magnetite.
