Coal preparation plant - Wikipedia

Coal needs to be stored at various stages of the preparation process, and conveyed around the CPP facilities. Coal handling is part of the larger field of bulk material handling, and is a complex and vital part of the CPP.. Stockpiles provide surge capacity to various parts of the CPP. ROM coal is delivered with large variations in production rate of tonnes per hour (tph).

Mineral processing - Wikipedia

Industrially, the most common dense media is a suspension of fine magnetite and/or ferrosilicon particles. An aqueous solution as a dense medium is used in coal processing in the form of a belknap wash and suspensions in air are used in water-deficient areas, like areas of China, where sand is used to separate coal from the gangue minerals.

Optimal coal processing route for the J 0.5 mm size fraction?

Alternative processing options When desliming the feed to the dense-medium cyclones at 3 mm, the coal in the desliming screen underflow reports to the fines stream. This coal is usually further deslimed with hydrocyclones to yield a nominal plus 100-micron size fraction, which is sent to the fine coal beneficiation circuit. In

Economic factors affecting coal preparation: plant design ...

The desliming step increased the net tonnage to 923 t/h, a net gain of 24 t/h over the base scenario (Case A). This represents nearly $6.5 million annually of additional revenues (24 t/h × 6000 h/year × $45/ton = $6.48 MM/year). Obviously, desliming to reject high-ash, high-moisture material is very attractive for this particular coal.
