Heavy Media Coal Separation

Dense-Heavy Medium Separation HMS / DMS Process

HMS and DMS are acronyms for Heavy (Dense) Medium Separation and is applied to the process of pre-concentration of minerals – mainly the production of a high weight, low assay product, which may be rejected as waste. In principle it is the simplest of all gravity processes and is a standard laboratory method for separating minerals of different specific gravity. Fluids of suitable density ...

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).

Heavy-media Cyclones for coal cleaning | FLSmidth

Like the heavy-media vessels, Heavy-media Cyclones also are designed to clean coal and minerals based on their density differences. Using finely ground magnetite and water as the media to create a buoyancy effect for gravimetric separation, the Heavy-media Cyclone forces the lighter solids to its centre, where the slurry transports them upward and through the vortex finder.
