مصنع لتجهيز البوكسيت/Coal Washing Gravity Separation Metho
Gravity separation is the most effective method for processing ore and coal such as gold, tungsten, and tin. It is also commonly used to recover rare rocks, ilmenite, rutile, zircon, monazite, coltan, and coltan, and nonferrous metal minerals, also used for sorting coarsegrained inlays and a few finegrained hematite ores and manganese ore ...
· Coal washing The raw coal extracted out from the coal mine is processed through different techniques to achieve the desired qualities. These result in higher economic value of run ofmine (ROM) coal.

Gravity separation method is based upon (A) Preferential washing of ores and gangue particles (B) ... Gravity concentration Webs Gravity concentration methods separate minerals of different specific gravity by their relative move ment in response to gravity and one or more other forces, the latter often being the resistance to motion offered by a viscous fluid, such as water or air.

A great many appliions of the washability curves are applied to cleaning operations in the coal preparation field (coal washing) so that most reference is made to coal washability ...
Modular Plants: Coal Мб. DMS plants can be used to recover both fine and coarse coal. A magnetite dense media solution is used as the separation medium, at specific gravities fromThese permit quick but comprehensive analyses of large sets of data on the washability of coal when separated by coal washing equipment.
A still further object of this invention is to provide a method for separating materials of different specific gravities and cleaning the material of lower specific gravity. Yet another object of this invention is to provide a method for washing coal in which relatively small quantities of waste water are discharged.

The difficulty in washing of coal is very much influenced by the amount of neargravity materials (NGM) present at the desired cut density. It is believed that the dense medium separation of coal particles in the presence of a high percentage of NGM results in a significant misplacement of .
Coal Washing, Magnetic Separation Processing. The dense medium separation process used in most coal washing and magnetic separation plants requires a suspension of finely milled magnetite in water. Magnetite for coal washing must be of overall high purity and be devoid of contaminants, such as hematite, sulphides or other minerals.
