Heavy Media Gravity Separation Mine Engineer.Com

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 than 2.5 will rise to the top and float.

Coal Beneficiation an overview ScienceDirect Topics

Coal preparation, or beneficiation, is a series of operations that remove mineral matter (i.e., ash) from coal. Preparation relies on different mechanical operations, which will not be discussed in detail, to perform the separation, such as size reduction, size classification, cleaning, dewatering and drying, waste disposal, and pollution control.

DenseHeavy Medium Separation HMS / DMS Process

Dense medium separation (or heavy medium separation (HMS), or the sinkandfloat process) is applied to the preconcentration 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 endproduct, clean coal being separated from the heavier shale or highash coal.
