    Magnetite dressing technology is mainly used for ore separating line with low taste in ore processing plant. Because the rocks have a strong magnetism and easy to grind, most of the ore processing plants adopt one stage and many stages process for crushing and grinding in ore beneficiation.It is used in Dense Medium Separation processes, where the powder is mixed with water to the desired medium density, and added to a DMS plant. The separation takes place in either a static (Drum) or a dynamic (cyclone) separating unit. Dense Medium Separation is also known as Heavy Medium Separation or the Sink-Float Process.

Clean coal being separated from the heavier shale or high-ash coal.In certain ores, gold and gangue may be separated by flotation. Finely ground ore is placed in a solution of chemicals and water. Some constituents of the ore are wetted by the solution and sink others are not wetted and float in a froth on top. Gold Refining. The gold yielded by ore-dressing processes remains alloyed with silver and trace.

    From float-sink tests of selected heavy minerals and Fe, Mn, and Cr ore samples. Low density difference between particles made the enrichment difficult using other gravity methods like jigs and shaking tables. After determining physical and mineralogical properties of the samples, appropriate size fractions were prepared for float-sink tests.Spiral classifiers or screw classifiers are important ore dressing equipment. Spiral classifier is mainly used in metal beneficiation production line to classify minerals according to their different sedimentation velocity. Screw classifiers can be divided into high weir type, low weir type and sank type according to the height of the weir.

    In the past coal maceral separation have been carried out based on density difference e. g., sink-float analysis, density gradient centrifugation (DGC) techniques etc. These approaches are of limited success. Froth flotation is a physico-chemical process separating particles on the basis of difference in surface properties in a vessel consisting of two distinct zones viz., pulp and froth zones.In this research, a gravity based separation method using heavy medium has been employed to recover Si from the solidified alloy. Although novel to this application, gravity separation methods are commonly practiced in ore dressing due to their low cost and simple operation.

    Introduction Heavy media separation (HMS), also called dense media or float sink separation, is one of the newer forms of gravity concentration. Though the concept can be traced to the last century, the process has enjoyed its major growth since 1940. Heavy liquid separation is a mutation.Sep 01, 2010 The float-sink separation is completed within 2 min. The float-sink separation is significantly affected by the size of the ore particles. Ore particles with size greater than or equal to 17.6 mm can be separated, whereas those less than 17.6 mm tend to scatter in the fluidized bed without floating or sinking.
