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).

gravity & density separators for minerals

Dense media separation utilises a medium with a density in between the density of the ore and the gangue (commercially worthless) particles. When introduced to this medium, particles either float or sink, depending on their density, as relative to the medium. Separation using this method relies solely on differences in density, without relying
