Anthracite coal has the highest carbon count and contains the fewest impurities of all coals, and has the highest calorific content as compared to other types of coals such as bituminous coal and lignite. Anthracite coal is a hard mineral coal that has the highest luster and lowest impurities of all coals. It is the cleanest variety of coals.

Coke is a solid carbonaceous residue derived from low-ash, low-sulfur bituminous coal from which the volatiles are driven off by heating without oxygen at temperatures as high as 1,000 °C (1,832 °F) so that the fixed carbon and residual ash are liquefied and fused together. Metallurgical coke is used as a fuel and as a reducing iron ore to iron in the blast furnace. The product is cast iron and is too rich in dissolved carbon, and so the carbon is reduced next in the steelmaking process.

Petroleum coke (pet-coke) is a carbonaceous solid derived from oil refinery coker units or other cracking processes. Non petroleum based cokes are made from coal.

A by-product of coal gas manufacture. Pitch coke is a high purity carbon residue created by coking coal tar pitch either by itself or in conjunction with other carbons when manufacturing carbonaceous products. Coal tar pitch is a by-product resulting from the thermal distillation of bituminous coal or graphite manufacturing. Because it is condensed from the gas phase, coal tar pitch is inherently low in ash, metals, and other non-carbonaceous substances. Pitch coke is extremely high in carbon and low in impurities. Pitch coke has a lower density than other comparable carbons.

Calcined Anthracite is manufactured by exposing high grade anthracite coal in various types of thermal or electrical ovens to temperatures as high as 2000 C, which results in some graphitic development in the finished product.

Amorphous graphite is formed by the thermal metamorphism of coal seams. Though crystalline in nature, its low degree of crystalline order and very fine particle size make it appear amorphous. It is usually of lower purity than the crystalline flake graphite and, therefore, commands a lower price than its crystalline counterpart.
