Use of Boron Compounds as Binders in Iron Ore Pelletization
In pelletizing, a mixture of iron ore, water and binder is rolled in a mechanical disc or drum to produce agglomerates (green balls or wet pellets). Green pellets then undergo a thermal process, which consists of three stages, namely drying (250 400oC), preheating (900 1100oC) and firing (1200 1300oC).
