Coal

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

COAL FLOTATION

Typical "Sub-A" coal flotation installation in England. The tailings from flotation are fed to a thickener where a flocculant is usually added to promote settling. The thickener underflow is pumped to multi-framed filter presses for removal of water to a final moisture content of 18-20%. This waste material is trucked to a disposal area.
