separation of steel dust from grinding sludge
STEEL INDUSTRY CO-PRODUCTS | worldsteel
The main solid co-products produced during iron and crude steel production are slags (90% by mass), dust and sludge. On average, the production of one tonne of steel results in around 200 kg of co-products for the electric arc furnace (EAF) route and 400 kg for the blast furnace - basic oxygen furnace (BF-BOF) route.
