  • Magnetizing Reduction and Magnetic Separation Studies on LowGrade Iron .

    Conventionally iron and steel is produced by the reduction of highgrade iron ores in a blast furnace. About 80% of the world's iron making is achieved through the blast furnace process and rest by different direct reduction (DR) processes. The role of highquality iron ore and concentrate as a raw material is very critical to get the best quality iron and steel [1].
