The most common media for separation is a fine magnetite suspension in water, ferrosilicon suspension, or a mixture of the two, depending on the required separation density. Magnetite alone is used when a density is required in the range from to g/cm 3, a mixture between and g/ cm 3, and ferrosilicon alone for a density range ...
Dense Media Separation Powder (Pty) Ltd "DMS" Overview DMS was acquired by a Siyanda – led consortium in 2005.

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 ferrousbased media recovery.
HMS 1 plant has the capacity to treat 100 tonnes of ore per hour (tph). In 2009 the Company commenced construction with DRA (a South African specialist manufacturer) of a second HMS plant at Etoile mine called HMS II which has been commissioned in August 2010. This is a sophisticated plant that also uses dense media.
To obtain this kind of separation, the material to be separated is immersed into a ''bath'' of a fluid of the proper density, in which the light components float, while heavy ones sink. According to the application, a suspension of powdered Ferrosilicon or Magnetite in water is used as fluid – heavy media – in order to allow the separation.
From the early 1960''s until the mid 1980''s, dense medium cyclone circuitry design technology did not change appreciably. The basic design, which was both highly flexible and highly efficient, was consistent with technology developed by the Dutch State Mines ("DSM") in the mid 1940''s. During this period, the "typical" dense medium cyclone circuit was designed to process raw coal ...
Feed to a heavy media vessel is injected perpendicular to the elongated width of the vessel; Float material travels across the vessel or is removed by a flight conveyor to one end. The high density particles sink and moved chain conveyor to other end. Dense medium separation [14530]

1 x 15 t/hr plant – 360 mm cyclone for recovery of material up to 25 mm ; Plant operating efficiency monitored using density tracers; In certain circumstances, dense media separation plants can be configured to follow complex gravity circuits, multi gravity separation and/or other separation techniques such as flotation.
These processes can be classified as either density separation or gravity (weight) separation. In dense media separation a media is created with a density in between the density of the ore and gangue particles. When subjected to this media particles either float or sink depending on their density relative to the media.
Feb 12, 2008· "The Bateman Modular Plant has become the benchmark against which others are measured," claims Robert Abate, Bateman General Manager, Modular Plants. "Besides a continued dominance in the market, Bateman Engineering won special mention awards in 2005 from the Southern African Institute of Steel for its drill chip sampling plant at the Venetia Diamond Mine and the dense media separation ...
