Wet Grinding And Dry Grinding For Ores And Minerals

Sep 01, 2019 Regarding the mineral surfaces, it was proposed that wet grinding of sulfides mainly deals with the chemical surface reaction of products while dry fine grinding mostly affects the oxidation of mineral surfaces . Feng and Aldrich (2000) also observed that the dissolution of Cu, Ni, and Pd from a platinum-bearing sulfide ore was higher after dry grinding compared with the wet process

    May 25, 2017 Dry Grinding VS Wet Grinding. The choice between wet and dry milling is, in general, unimportant in small-scale milling but is a major technical problem when large-scale milling in the metallurgical industries is involved. On purely mechanical grounds it is difficult to see any great difference in fundamental principles between wet and dry milling, since dry milling may be regarded as wet milling with a fluid having the viscosity and density of air, whereas with wet milling

    Abstract. Though most ores are reduced by wet grinding before being processed, some can better be ground and treated dry. Many minerals and synthetic substances require size reduction only. Other grinding problems arise in which chemical instability, contamination, corrosion or risk of explosion call for special precautions, such as milling in an inert atmosphere or one where moisture is undesirable or
