Removal Hematite From Silica Sand Processing

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 10,000.
