Heavy Media Separation an overview | ScienceDirect Topics

Heavy media separation dates back to several centuries Initially, a fine magnetite was used as a heavy media In 1936, a plant was designed employing organic liquid as a heavy media for treating anthracite coal containing ore The heavy media process is usually used for treatment of21052016· The heavymedia separation process, or HMS, employing ferrous media, usually ferrosilicon and/or magnetite, is the most generally used process for sinkfloat separations A stable medium over the range of specific gravities from 125 to 340 can be maintained within close limits and is cleaned andHeavy Media Separation Process 911 MetallurgistHeavy 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 sinkandfloat separationHeavy media separation with dense Magnetite | LKAB
