heavy media separation iron ore bentonite; heavy media separation iron ore bentonite. Patent US3865240 Purification of bentonite Google Patents. Finely comminuted, crude bentonite may be purified of accompanying quartz, muscovite, illite, feldspar, iron oxide and like impurities by pouring an aqueous slurry of liquid and the purified bentonite suspended therein are separated from each
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. Finer coal below 9.5 mm cannot be cleaned
Dense medium separation (or heavy medium separation (HMS), or the sink-and-float process) is applied to the pre-concentration of minerals, i.e. the rejection of gangue prior to grinding for final liberation.It is also used in coal preparation to produce a commercially graded end-product, clean coal being separated from the heavier shale or high-ash coal.
Bentonite Used In Mining Of Iron Ore . We are a large-scale manufacturer specializing in producing various mining machines including different types of sand and gravel equipment, milling equipment, mineral processing equipment and building materials equipment. And they are mainly used to crush coarse minerals like gold and copper ore, metals like steel and iron, glass, coal, asphalt, gravel
The heavy-media separation process, or HMS, employing ferrous media, usually ferrosilicon and/or magnetite, is the most generally used process for sink-float separations. A stable medium over the range of specific gravities from 1.25 to 3.40 can be maintained within close limits and is cleaned and recovered by magnetic means.

Dense Medium Separation (also called Heavy Media Separation) is a well-established density separation process. Dense Medium Separation (DMS) uses the characteristic differences in density of the input material to enact a gravimetric-based separation. Due to the robustness of the process, DMS can be used in the separation of minerals, ore bodies
Heavy media gravity separation involves using a mixture of fine media material, such as magnetite (SG 5.1) or ferrosilicon (SG 6.8), suspended in a slurry of water, to produce a media slurry with a specific gravity that will allow low density material(s) to float, and other high density material(s) to sink. T he SG of separation is the SG of the media slurry, and can range from 1.45 (for coal
