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 …
