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.
new dense-medium cyclone plant at Tertre in Belgium to process 10 x 0 mm raw coal. The plant was unique in that the feed to the plant was not de-slimed before processing. The raw coal was mixed with magnetite and gravity-fed to two 500 mm diameter (D) cyclones at a feed pressure of 9D. The minus 0.75 mm coal in the feed drained through

Processing the Coal. After coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is located at the mining site. The plant cleans and processes coal to remove dirt, rock, ash, sulfur, and other unwanted materials, increasing the heating value of the coal. Source: Energy Information Administration
Coal mining - Coal mining - Coal preparation: As explained above, during the formation of coal and subsequent geologic activities, a coal seam may acquire mineral matter, veins of clay, bands of rock, and igneous intrusions. In addition, during the process of mining, a portion of the roof and floor material may be taken along with the coal seam in order to create adequate working height for ...
