Heavy media separation with dense Magnetite LKAB Minerals®

Principles of heavy media gravity separation. Heavy media gravity separation means separating products with different densities. Both magnetite and water are used to make a slurry on which one product will float (the product with a lower density than the slurry) and in which the other product will sink (the product with a higher density than the slurry).

Magnetite recovery in coal washing by high gradient

Magnetite, slurried in water, is used to create an apparent heavy medium in which fine coal (0.1 to 2.4 mm) is cleaned of its mineral impurities. The magnetite is much finer in size (1 to 44 ..mu..m) than the coal and is usually recovered from the coal and refuse by magnetic drum separators.
