Coal Analysis and Production Information - Thermo Fisher Scientific Coal is a common energy source in the steel industry to extract iron from iron ore, and in the cement production process. The four main types of coal are lignite, sub-bituminous, bituminous, and anthracite. Each type has varying amounts of hydrogen, oxygen, nitrogen, sulphur, and carbon, and as a result they have different uses.
