2019-9-1  Dry grinding has significantly lower media and liner wear than wet grinding; thus, the Fe concentration in the pulp of downstream process for the same mineral is relatively lower after dry grinding. Dry grinding produces rougher surfaces (mechanically activated centers) and more agglomerated particles than wet grinding.

2011-1-1  The median particle sizes of product obtained for the grinding limit in wet and dry conditions were around 0.5–0.6 μm and 2 μm, respectively. The width of the particle size distribution in wet grinding decreased with decreasing median particle size of the ground product, and the size distribution in dry grinding became nearly constant.

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.
