raw coal requirement for producing one metric ton of sponge iron

Sponge Iron - an overview | ScienceDirect Topics

Around 150 kg of coal are used to produce 1 tonne of steel in electric arc furnaces. Other steel production methods Pulverised coal injection. Pulverised Coal Injection (PCI) technology involves injecting coal directly into the blast furnace to provide the carbon for iron-making – displacing some of the coke required for the process.
