Heavy Media Separation an overview | ScienceDirect Topics

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.

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).

Dense Media Separation QMAG

With magnetite, though, producers can use basic physics to separate the valuable from the worthless while reducing harmful and even toxic byproducts, through dense media separation (DMS). Also known as Heavy Medium Separation, DMS is a technique first pioneered in the 1950s in coal refineries that relies on varying densities of a desired product.
