The fundamentals of the smelting process rely on the reaction between the basic ingredient iron ore, and the transmuted ingredient coke derived from metallurgical coal. Coke is created by a coking process involving the heating of metallurgical coal to 1100 to 1400 °C in the absence of oxygen [ 8 ] which enables the removal of impurities ...
