optimization studies for vertical roller mills

  • Research on new beneficiation process of low-grade

    2020-4-14 · 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 parameters and then performed closed-circuit beneficiation
