major coal cleaning devices are shown in Figure 1. Typical efficient separating gravity ranges are given in Figure 2. For below about mm raw coal fines, the difference of surface property is utilized since conventional gravity dependent processes are inefficient for this size range. Coal preparation plants are designed to suit their

· In heavymedia separations, the specific gravity of the medium used for separation, usually a suspension of finely divided magnetite in water, is chosen to achieve a given degree of separation depending on the characteristics of the coal, the desired product quality, and the acceptable level of coal loss to the rejects.

Shaking tables are one of the oldest gravity separators in the mineral processing industry, capable of handling minerals and coal of 02mm. Shaking tables are rectangularshaped tables with riffled decks across which a film of water flows. The mechanical drive imparts motion along the long axis of the table, perpendicular to the flow of the water.

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 ...

· · The sand used is sized between 150 and 600 μm and when fluidized by water rising at 6–12 mm/s the density is in the range – and hence is suitable only for coal/shale separation. Gravity control is achieved by varying the water flowrate.
