Gangue, also called coal gangue, is the solid waste discharged in coal mining process and coal washing process, black rock harder than coal. Its carbon content is low and exists along with coal seam. Gangue could be found in roof, bottom board, inter-layer, and it could be selected in washing process. The main ingredient are Al2O3, SiO2, Fe2O3, CaO, MgO, Na2O, K2O, P2O5, SO3 and rare elements

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.
