Mineral Sands Process Development

Heavy Liquid Separation This type of gravity separation is also known as “sink-float” separation. The heavier particles will sink and effect sharp separation of the heavy and light particles. In practice, the dense media (i.e. bromoform at 2.84-2.89, tetrabromomethane at 2.94, or lithium heteropolytungstates at 2.85) are used in

Heavy Media Separation an overview ScienceDirect

39.3.3 Heavy media separation 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 of coarse coal above 9.5 mm in size.
