Coal, fossil coal, is a solid sedimentary rock, a combustible mineral formed by the carbonization of plant residues under pressure and high temperatures without access to oxygen. It is one of the most common minerals in nature and the most widely used by humans. Coal is a valuable fuel and raw material for the metallurgical and chemical industries.<\/p>\n<\/div>\n\n\n\n

Lignite is a solid combustible mineral, the lowest member of the carbonization series of fossil coals, hypothetically a transitional form from peat to coal. The color is from light brown to black. Calorific value of combustible mass is 24\u202631 MJ\/kg. It has low hardness and high hygroscopicity.<\/p>\n<\/div>\n\n\n\n
