— We investigated whether the vertical roller mill can be efficiently used in the beneficiation of low-grade magnesite and whether it can improve upon the separation indices achieved by the ball mill. We conducted experiments involving the reverse flotation and positive flotation of low-grade magnesite to determine the optimum process …
— The hematite ore processed by a beneficiation plant in India has an uneven grain size and gangue minerals as quartz. It adopted a combined process of stage grinding and gravity separation-magnetic separation-reverse flotation. After one stage of grinding, nearly 60% of the coarse-grained concentrate and tailings were obtained.
