  • Steel manufacture

    On average the production of 1 tonne of steel results in 200 kg (EAF) to 400 kg (BF/BOF) of byproducts. The main byproducts produced during iron and crude steel production are slags (90%), dusts and sludges. The worldwide average recovery rate for slag varies from over 80% for steelmaking slag to nearly 100% for ironmaking slag.
