Coking Coal for steel production and alternatives - Front ...

The coke is fed into a blast furnace along with ‘raw’ iron ore and some other minerals called fluxes. This produces pig iron. Pig iron is the basic ingredient to produce steel. Coal therefore plays three roles in the production of steel: a reducing agent, to turn the pig iron to coke; a source of energy to drive the process by breaking apart molecular bonds; and a source of carbon for the ...
