Gravity separation process is used for the concentration of haematite. Gravity method is based on the difference between the densities of the ore particle and gangue. It is used for the concentration of denser ores from the water soluble and lighter impurities (gangue). Oxide ores and carbonate ores are concentrated by this method.

Gravity separation methods can remove the low density silica and alumina minerals and magnetic separation is required to improve the Mn/Fe ratio of concentrate. A 2-stage high intensity magnetic separation process can recover 35-40% of feed material with the 42% Mn and Mn/Fe of 5 at 47-49% manganese recovery.

The principal separation in iron ore beneficiation, therefore, is between the iron minerals, hematite and/or magnetite, and silica, principally in the form of quartz. The use of flotation, either alone or in combination with magnetic separation, has been well established as an efficient method for rejecting silica from these iron ores.

The beneficiation of a hematite ore fines with magnetization roasting and magnetic separation was proposed and studied. The magnetic properties of ore can be enhanced due to the selective conversion of hematite and siderite into magnetite. Magnetization roasting can be applied effectively for the processing of carbonate-containing hematite ore.
