Dense Medium Separation Iron Ore
The art and science of dense medium selection Iron ore in the form of haematite, pure iron ore has a particle density of 52 t/m3 and it is separated from siliceous material with a particle density of 265 t/m3 The mixture of ore and medium is introduced into separating vessels within which the separation In dense media separation a media is created with a density in between the density of the ore and gangue particles When subjected to this media particles either float or sink depending on their density relative to the mediaMineral processing WikipediaDensemedia separation (DMS) processes have shown promise as a preconcentration stage and has been incorporated into platinumgroup metals flowsheets, to separate barren waste rock from ore prior to milling The beneficiation of chromite and iron ore using gravity and magnetic separationPhysical Separation MintekKumba already has a dense media separation plant that processes lowgrade, nonDSO ore and separates it to higher grade iron ore at Kolomela (pictured)Kumba plans Sishen UHDMS iron ore project kick off HMS and DMS are acronyms for Heavy (Dense) Medium Separation and is applied to the process of preconcentration of minerals – 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 separating minerals of different specific gravity Fluids of suitable density DenseHeavy Medium Separation HMS / DMS Process

Dense Media Separation of Diamonds – DMS Powders
Dense Media Separation is a wellknown sinkfloat method and technology used within the coal, iron ore and diamond industries In the process of Dense Media Separation in diamonds, a powdered ferrosilicon (which is an alloy of iron) is suspended in water to form a very defined pulp density (heavy liquid), close to the density of diamond (352 g Iron ore plants currently in the design stage provide the following capital costdata: Bathtype separation plants R2000R2500 per tonne per hour throughout Centrifugaltype separation plants R6000R7000 per tonne per hourthroughout The operating costs of plants treating, say, plus 25 mm and minus 6 mm material are in the same ratio asare the Theuseofheavymediumseparationinthe Dense Medium Separation (also called Heavy Media Separation) is a wellestablished density separation process Dense Medium Separation (DMS) uses the characteristic differences in density of the input material to enact a gravimetricbased separation Due to the robustness of the process, DMS can be used in the separation of minerals, ore bodies Heavy Media Separation Process (ferrosilicon) DMS PowdersHeavy Media Gravity Separation Heavy media gravity separation involves using a mixture of fine media material, such as magnetite (SG 51) or ferrosilicon (SG 68), suspended in a slurry of water, to produce a media slurry with a specific gravity that will allow low density material(s) to float, and other high density material(s) to sinkHeavy Media Gravity Separation Mine The stability of a ferrosilicon dense medium suspension is one of the most important parameters to keep under control since it determines the density gradient of the medium in the separation zone (PDF) The stability of ferrosilicon dense medium suspensions
