Iron Ore Sinter - an overview ScienceDirect Topics

Sintering and pelletizing are two common agglomeration processes. In a BF, pig iron and blast furnace gas (BFG) is produced by reducing iron ore sinters and pellets with coal and coke. BFG is partly used for other processes within the iron and steelmaking plant, and the rest can be exported for power generation.
