They are the starting materials for the technical extraction of pig iron in the blast furnace. The blast furnace operates at 1900 °C in order to smelt iron from iron ore. To attain that temperature, coke (and not coal) is used as fuel, and the fire inside the furnace is fanned with hot air at 1200 °C to 1300 °C degrees.

Recycling of Ferrous By-products in Iron and Steel Plants

Significant amounts of by-product fines are produced and collected in steel plants at all steps of iron & steelmaking. It can be assumed that per ton of steel produced around 60 -150 kg of particulate by-product is generated. Considering that these by-products have an average iron content of >50%, this is 3 up to 7,5% of the total steel production.
