Processof Reduced Grade Iron Ore In Steel Mills Mining

Most steel mills use a blend of different grades of ore, and a mix of sinter, lumps and fines, but the quality requirements depend on the circumstances and availability. For example, ore used in the direct reduction process to make direct reduced iron (DRI) or hot briquetted iron (HBI) destined for melting in an electric arc furnace (EAF) needs.
