The low grade of iron ores contains high amount of alumina (Al2O3) and silica (SiO2). The main problem is to extract the clay particles from the ores. According to IBM a plant cannot throw above 45% grade of iron ores due to environment effects. Thats makes new challenges for recovery of iron values from low grade of iron ores.

Once the iron ore becomes magnetite, it is much easier to beneficiate & pelletise it. The efficiency of iron recovery is 90-95% (as against 70-75% in the conventional beneficiation plants) & the left-over Fe in the tailings is only 10-15% (as against 35-45% in the conventional beneficiation plants).
