Anthracite Coal
Anthracite Coal is a hard, compact coal that has sub-metallic luster. It also contains the highest level of fixed carbon, the lowest level of impurities, and the highest energy density among all types of coal except graphite. These properties help make it suitable for many metallurgical applications. Smaller sizes such as #5 and barley are utilized for injection into electric-arc furnaces to aid in foamy slag production. Larger sizes such as pea, buck, nut and stove are utilized as charge carbon.
