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 concentrate. The more economical beneficiation method is gravity separation, which is a strong magnetic separation, but it is difficult ...
