The stability of ferrosilicon dense medium suspensions

Dense medium separation is the process in which a heavy liquid of an intermediate density is used to separate minerals of different specific gravity. The heavy liquid is typically a suspension of dense powder such as ferrosilicon or magnetite in water. Ferrosilicon is used for high-density applications (medium density: 3200–4200 kg/m3).

Jun 23, 2015 Dense medium separation (or heavy medium separation (HMS), or the sink-and-float process) is applied to the pre-concentration of minerals, i.e. the rejection of gangue prior to grinding for final liberation. It is also used in coal preparation to produce a commercially graded end-product, clean coal being separated from the heavier shale or high-ash coal.

The potential for dense medium separation of mineral fines

May 01, 2017 Dense medium separation (DMS) is a process by which particles are separated based on differences in specific gravity (SG). The process can be controlled with a high degree of precision over a wide range of separating densities and is commonly applied as a pre-concentration step for minerals (such as cassiterite) and in the separation of coal from contaminants ( Wills and Finch, 2016 ).
