Metallurgical coke is a solid fuel product obtained by carbonizing coal at high temperatures (destructive distillation). This product is produced by heating bituminous coal to temperatures between 500 and 1100 degrees Celsius. The ideal properties of metallurgical coke include a high fixed carbon ratio and low ash, sulfur and phosphorus ratios. These characteristics make it highly valuable for industrial uses.

In the iron and steel production process metallurgical coke plays a critical role as both a reducing agent and an energy source. Metallurgical coke provides the high temperatures required to reduce iron ore making it an indispensable component in iron and steel production. Its high carbon content and low sulfur and ash ratios make metallurgical coke an ideal raw material for high quality steel production.
