The Alberta government began its fraught push for coal nearly a year ago, when the province's United Conservative Party government announced it had done away with a 1976 policy that prevented open-pit coal mining in much of the Rocky Mountains. New mines in the region would produce metallurgical coal, used for steel-making. Backlash ensued.

Making steel. Steel is made from iron ore, a compound of iron, oxygen and other minerals that occurs in nature. The raw materials for steelmaking are mined and then transformed into steel using two different processes: the blast furnace/basic oxygen furnace route, and the electric arc furnace route. Both processes are being continually improved ...

From there, the coal is converted into coke and then used in the blast furnace-basic oxygen steelmaking process. Coal does three things in this process: it is burned to supply the huge amounts of heat required, it supplies gases to strip oxygen from the iron ore and roughly 1% of the coal ends up as carbon in the steel.

Metallurgical (met) coal (or coking coal) is a naturally occurring sedimentary rock found within the earth's crust. Categories of met coal include hard coking coal, semi-hard coking-coal, semi-soft coking coal and pulverised coal for injection (PCI). These apply to the different quality grades of met coal, all of which are used to make steel.
