In dense-medium separation, the a carrying medium is a mixture of water, magnetite, or ferrosilicon.The paramagnetic properties of the medium allow it to either remain in suspension at a predetermined slurry density or to be separated from water for cleaning and reuse.Magnetic Separation – separation based upon natural or induced .
In gravity separation operation, the probability of a coal particle to appear in the product stream or in the refuse stream is a strong function of its size.Improper selection of feed size may lead to significant reduction in efficiency of the separation unit.Available literature conforms that the separation efficiency of an air dense medium fluidized bed separator, which is a gravity .
In the field of extractive metallurgy mineral processing also known as ore dressing is the process of separating .In practice particle size and shape can affect separation efficiency.Industrially the most common dense media is a suspension of fine magnetite and/or ferrosilicon particles.
