  • Heavy Media Gravity Separation

    T he SG of separation is the SG of the media slurry, and can range from 1.45 (for coal), to around 2.8 (for diamonds). The separation principal is very simple, if the "liquid" media has a SG of 2.5, every mineral with a SG greater than 2.5 will sink and those lighter

  • Heavy Media Separation Process

     · Three processes have been proposed that use true heavy liquids; the Lessing process, the Bertrand process, and the Du Pont (Nagelvoort) process. The Lessing and Bertrand processes clean coal in a solution of calcium chloride, and the Du Pont process uses organic liquids of high specific gravity.

  • Dense-Heavy Medium Separation HMS / DMS Process

     · The low SG range of liquids are used for coal/ash samples, while most mineral samples are separated in the range 2.50 to 4.0. [Suspensions of ground material (known as media – usually magnetite, S.G. 5.1, and/or ferrosilicon, S.G. 6.8) are used on larger scale laboratory samples and in industrial applications.]
