Coal Anthracite, Bituminous, Coke, Pictures, Formation, Uses

Coke production remains an important use of coal. Coke is produced by heating coal under controlled conditions in the absence of air. This drives off some of the volatile materials and concentrates the carbon content. Coke is then used as a high-carbon fuel for metal processing and other uses where an especially hot-burning flame is needed.
