Most beneficiation plants in India are just washing material to discard liberated silica and alumina as micro fines using various stages of washing. Currently, India is at the border of a phase transformation from high-grade to medium/low-grade ores because of depletion of high-grade iron ore. The low-grade ores are highly contaminated with alumina
Because the theoretical iron grade of limonite is low, and often with calcium and magnesium, manganese is a homogeneous symbiosis. Hence, using physical beneficiation methods, iron ore concentrate grade is challenging to reach more than 45%, but after roasting because of the large burn loss and significantly improves the grade of iron ore ...
