effect of size at coal beneficiation plant

Coal Beneficiation - an overview ScienceDirect

The hard coal beneficiation process in mechanical preparation plants generates coarse, small or fines rejects and coal tailings slurries. The tailings are the finest grain size, with the majority below ~ 0.25 mm, whereby material sized below 0.035 mm makes up to 60% share in the slurry composition.

Coal preparation plant - Wikipedia

A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships.

Beneficiation - Wikipedia

Beneficiation can begin within the mine itself. Most mines will have a crusher within the mine itself where separation of ore and gangue minerals occurs and as a side effect becomes easier to transport. After the crusher the ore will go through a grinder or a mill to get the ore into fine particles.

Heavy liquids (mostly organic compounds), heavy particles, sands etc., are commonly used for heavy media. All coal beneficiation plants at present are using magnetite as heavy media. It plays a vital role for maintaining high specific gravity.
