Research on new beneficiation process of low-grade ...

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 ...

Beneficiation of low-grade, goethite-rich iron ore using ...

2021-6-1  The use of a gaseous reductant to convert goethite to magnetite in low grade iron ore fines offers additional advantages over conventional reductants such as coal or coke. For example, traditional ironmaking processes such as the blast furnace emit large volumes of CO 2 contributing significantly to the global carbon budget.
