Abstract
At Kalyadi concentrator plant the ROM ore is required to be reduced to 70% - 200 mesh size for liberation of valuable mineral. The metallic minerals that are mainly present in the ore are chalcopyrite, pyrite, magnetite and pyrrhotite the latter two being of minor occurance within quartzite. These minerals occur as disseminations, specks, particles, thin veinlets and concentrations. Ore is highly abrasive in nature with specfic gravity of 2.9. Ore grade varies from 0.5 to 0.8% Cu. giving an average grade of 0. 65% Cu.
