Majority of the recent investigations on flotation of fine coals have been conducted with coal feeds obtained by either dry grinding or wet grinding. 1-1 Therefore, theMinerals | Free Full-Text | Comparison of Wet and Dry,Wet grinding technology in EMM has been showed to be more effective than the dry technology. When the energy required for the pneumatic and hydraulic transport system is compared, that difference is even clearer. Research on dry grinding is, however, necessary, because some material can only be grinded in dry technology.A comparative study on the effects of dry and wet grinding,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.
