blast furnace waste processing

An integrated steel plant generates a large amount of blast furnace flue dust - about 18-22 kgt of hot metal - as a by-product of the production process. The major component of this flue dust is iron oxides and coke fines. The recovery and reuse of this iron and coke is very important with increasing price of conventional resources.
