Iron Recovery and Dephosphorization Behaviors from High-Phosphorus Oolitic Hematite by Gas-Based Direct Reduction and Magnetic Separation

With the depletion of high-quality iron ore resources, high-phosphorus oolitic hematite (HPOH) has attracted great attention due to its large reserve and relatively high iron content. However, HPOH is very difficult to be used in ironmaking process due to its special structure. A two-step method of gas-based direct reduction and magnetic separation was thus proposed to recover iron and reduce phosphorus. The results showed that the powdery reduced iron produced contained 92.31
