Iron processing

Sintering. Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together. For this purpose, a traveling-grate machine is used, and the burning of fine coke (known as coke breeze) within the ore generates the necessary heat.Before being delivered to the sinter machine, the ore mixture is moistened to cause fine particles to …

Catalytic reforming of volatiles from co-pyrolysis of lignite blended

In the process of catalytic cracking of volatiles, not only can the tar quality be improved, but the iron ore itself is also reduced, thereby improving the grade of the iron ore. More importantly, reduced iron can be used as a premium raw material for ironmaking. To date, the greatest challenge in ironmaking has been excessive CO 2 emissions.
