This method is particularly effective for low-grade ores where the iron content is not very high. Another common method of beneficiation is through magnetic separation, which exploits the difference in magnetic properties between iron minerals and gangue minerals. By subjecting the crushed ore to a magnetic field, the iron-rich …

Gravity separation is one of the oldest concentration methods used in mineral beneficiation practices. It utilizes differences in the specific gravity of valuable and gangue minerals to achieve the separation. Taggart has proposed a "concentration criterion," which is widely used to evaluate the feasibility of gravity concentration:
