Dense Medium Separation Ideal for Processing SR and Zorba
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.
Gravity separation - Wikipedia
Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force.

1. Introduction - Hindawi Publishing Corporation
Heavy media separation (HMS) method has been demonstrated to be effective for separating high-quality RCA from mixed CDW by means of sink-float separation in a heavy liquid. The heavy liquid recommended in ASTM C123  includes zinc chloride (ZnCl 2) in water, 1,1,1,2-tetrabromoethane (C 2 H 2 Br 4), and zinc bromide (ZnBr 2) in water.
Gravity Separation - an overview | ScienceDirect Topics
Gravity separation has been applied to process chrome slag by steel researchers in India. Heavy media separation (Choudhury et al., 1996) and crushing and jigging (Khan et al., 2001) are the principal techniques used. The slag is subjected to 2-stage crushing to reduce the size to −10 mm and then screened into −10 +1 mm and −1 mm fractions.
Heavy-media separation | Britannica.com
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 ...
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.
