Blast Furnace - an overview | ScienceDirect Topics

The blast air causes the iron oxides, flux, and coke to react and iron, carbon monoxide and blast-furnace slag is produced. The molten iron and blast-furnace slag is collected at the base of the furnace, while the gases are recirculated for fuel in the sinter process, after separation of particulate material ( Cooper, 2005 ).
