furnaces. For typical iron ore grades (60% to 66% iron), a blast furnace normally will produce about 0.25 to 0.30 metric tons (t) of slag per metric ton of crude or pig iron produced. For ores of lower than average grade, the slag output will be higher, in some cases as much as 1.0 to 1.2 t of slag per ton of crude iron.

How Do You Turn Iron into Steel? Metro Steel

Pig Iron. To create pig iron from the raw material which can be used, iron ore, coke, and small amounts of flux to draw out the impurities, are fed into a blast furnace. The furnace is then blasted with hot air at a temperature of about 1200C. This makes the coke burn, which in turn produces carbon monoxide, which then reacts with the raw iron.
