alumina aration from silica gold ore


Removal of Silica and Alumina as Impurities from Low-Grade Iron Ore Using Wet High ... , 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 ...
