    Removal Of Silica And Alumina As Impurities From Low

    This study investigates the removal of silica and alumina as impurities from hematite based low-grade iron ore containing 34.18 mass iron 31.10 mass of silica and 7.65 mass alumina. Wet high-intensity magnetic separation WHIMS and reverse flotation RF were investigated. In WHIMS process 93.08 of iron was recovered with a grade of 53.22 mass at an optimum magnetic density of
