Heavy Media Separation Process Equipment - Alibaba.com. The Heavy Media Separation Process Equipment is an open tank filled with water with a thick bed of particles, called ragging, supported on a horizontal perforated surface as below.
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.

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.
In heavy-media separation (also called sink-and-float separation), the medium used is a suspension in water of a finely ground heavy mineral (such as magnetite or arsenopyrite) or technical product (such as ferrosilicon). Such a suspension can simulate a fluid with a higher density than water. When ...

Heavy Media Gravity Separation 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.
Oct 23, 2014· With our heavy media system we are able to separate Zorba into aluminum, heavy metals and a mix of magnesium and waste. "We do this by separating the material in two density steps," continues Waignein. "Our system uses a first separation drum which has a fluid (medium) inside it with a specific gravity (SG) of 2.2.
