Dense Medium Separation - An Effective and …

Dense medium separation (DMS), synonymous with heavy medium separation (HMS), is a form of gravity concentration technology involving float-sink separation that historically has been used predominantly in the coal and diamond processing industries.

Palabora Mining Company Ltd

Current magnetite production is a by-product of the copper operations and as such is recovered from the Concentrator floatation tails stream by magnetic separation. Approximately 15%, by weight, of magnetite is removed by 'cleaning' and 're-cleaning' of the magnetic concentrate from the first stage.

Processing Methods | Diamcor Mining Inc.

In a Dense Media Separation (DMS) plant, powdered ferrosilicon (an alloy of iron and silicone) is suspended in water to form a fluid near the density of diamond (3.52 g/cm3), to which the diamond bearing material is added to begin the separation process of the heavier minerals from the lighter material.
