Heavy media separation with dense Magnetite LKAB

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). Hence our customers often use the term sink-and-float separation.
