  • A comparative study on the effects of dry and wet grinding

    Sep 01 2019 · Surface roughness particle agglomeration and surface oxidation are higher in dry grinding than wet grinding which all these effects on the flotation process. Moreover dry ground samples in the pulp phase correlate with higher Eh and dissolved oxygen concentration. Therefore dry grinding can alter the floatability of minerals.
