In 1936, a plant was designed employing organic liquid as a heavy media for treating anthracite coal containing ore.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).Heavy Media Separation Process,The Sink and Float separation process is part of what is also known as a Heavy Media Separation Process (HMS) and are commercial adaptations of the common laboratory procedure used for separating a mixture of two products having differentials in specific gravity by immersing the sample in a heavy liquid having a gravity intermediate to those of the products to be separated. The lighter,
