Coal facts NRCan
Coal facts. Coal is an organically derived material. It is formed from the remains of decayed plant material compacted into a solid through millions of years of chemical changes under pressure and heat. Its rich carbon content gives coal most of its energy content. When coal is burned in the presence of air or oxygen, heat energy is released.

Energy Use in US Steel Manufacturing Stanford .
Iron ore is mixed with coke, a form of very pure coal. The blast furnace burns the coke to heat the iron ore causing it to react into iron (Fe 2 ), nitrogen (N 2 ), and carbon dioxide (CO 2 ). This iron is often known as "pig iron" or "hot metal" as it is a liquid iron that flows from the bottom of the blast furnace.

Strip Mining an overview | ScienceDirect Topics
Andrew P. Schissler, in Encyclopedia of Energy, 2.3 Strip Mining. Strip mining is employed in coal reserves where the overburden is removed in rectangular blocks in plan view called pits or strips. The pits are parallel and adjacent to each other. Strip mining is fundamentally different from contour or area mining on how the overburden is displaced, called spoil handling.
