Beneficiation of iron ores ispatguru. the process adopted to upgrade the fe content of iron ore is known as iron ore beneficiation iob. however, iron ores from different sources have their own peculiar mineralogical characteristics and require the specific beneficiation and metallurgical treatment to get the best product out of it.
Depending upon the origin and mineralogical characteristics of the ore, beneficiation methods vary from simple crushing and screening to complex concentration processes. basically, the processes based on gravity and magnetic separations and flotation have been used for concentration of low grade iron ores.
