Ore-Based Metallics for iron & steel

Pig iron is produced principally by the reduction of iron ore in a blast furnace, using coke or charcoal as reductant. In integrated steel mills, liquid iron (hot metal) is transferred directly to the steel plant for refining into steel. For the merchant market, liquid iron is cast into ingots which when cooled can be delivered to customers.
