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

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 ionic flotation route. The lowgrade iron ores contain high grades of silica and alumina.

Summary: The loss of ironbearing minerals to the tailings, especially in the finest fractions (−44 μm), is a problem that must be endured due to the depletion of deposits containing highFe hematite. The two main mechanisms for iron mineral loss in the froth in reverse ionic flotation are hydrodynamic dragging and true flotation.
