Concentration is performed by combiningdense medium separation(DMS) with XRT (transmitted X-ray), pulsed X-ray,mineraljigs according to application and condition. Using conventional X-ray technology, pulsed X-ray technology or XRT for the final recovery of diamonds.Processingof …
Dense medium separation(orheavy medium separation(HMS), or the sink-and-floatprocess) is applied to the pre-concentration ofminerals, 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

HMS and DMS are acronyms for Heavy (Dense)Medium Separationand is applied to the process of pre-concentration ofminerals– 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 separatingmineralsof different specific gravity. Fluids of suitabledensity
