Laboratory studies on ball wear in the grinding of a

As the Kudremukh ore contained about 0.2 pyrite, the effect of addition of pyrite on ball wear was studied separately. Results of marked-ball grinding tests indicated that ball wear increased with time and showed a sharp increase for wet grinding over dry grinding. Ball wear under wet grinding conditions was also influenced by the gaseous atmosphere in the mill. At 70 solids, the best results in terms of
