chromite heavy medium separation

Gravity and heavy medium separation GTK

Gravity and heavy medium separation methods are used when separating minerals with different specific gravities. Typical examples of such industrial minerals include chromite and kimberlite. The method is also used in precious metal and sulphide ore combination processes and in a variety of recycling processes as an auxiliary method.

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.

Dense Medium Separation - An Effective and Robust Pre ...

Dense medium separation (DMS) is a robust process that can be conducted at particle sizes as coarse as 300 mm and as fine as 500 µm with high separation efficiency, depending on liberation characteristics of the value minerals. The DMS process involves three steps: feed preparation, dense medium separation, and ferrous-based media recovery.

Heavy Media Separation Process

May 22, 2016  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.

The low chromium-to-iron ratio of chromite ores is an important issue in some chromite deposits. The value of the chromite ore is indeed dictated in the market by its iron, as well as its chromium content. In the present study, a chromite concentrate was reprocessed by gravity (spiral concentrator) and magnetic separation to enhance the chromium-to-iron ratio.
