Effect of Ore Pulp Density and pH Value on Silica in Iron Ore

Iron ore flotation is an efficient method to remove impurities from iron ore. Some amount of silicon dioxide is found in the ore even after separation from the magnetic and hydraulic mechanism. The most widely used method of flotation is the reverse cationic flotation route. The low-grade iron ores contain high grades of silica and alumina.
