The dry dense medium separation of iron ore based on floating and sinking of ore particles in a gas–solid fluidized bed was investigated using zircon sand as the fluidized medium. The float-sink of ore particles with mean size D ave = 23.6 mm was investigated as the fluidizing air velocity and the float-sink time were varied. It was found that gangue with density less than 2850 kg/m 3 which float is able to be separated from valuable ore with density

Dense Medium Separation (DMS) Mineral Processing Methods MRT 361-2 Mineral Resources & Technology Degree Program Uva Wellassa University Sri Lanka. f Aim of This Method  To separate the ore samples into a series of fractions according to density, establishing the relationship between the high and the low specific gravity minerals. f Introduction  Dense medium separation or the sink-and- float process is applied to, 1)pre-concentration of minerals,  Rejection of gangue prior to grinding for final liber- action. 2)Used in coal preparation to produce a commercially graded end-product.  Clean coal being separated from the heavier shale or high-ash coal. fPrinciple  This process is simplest of all gravity processes, for separating minerals of different specific gravity.  Heavy liquids of suitable density are used to separate minerals, Minerals lighter than the liquid tend to float, Minerals which denser than the liquid it sink fTo Where DMS is Applicable?  DMS is applicable to any ore

Dense-Heavy Medium Separation HMS / DMS Process

2015-6-23 · 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.
