Includes bibliographical references. "Samples collected in September, 1979, from the secondary zinc circuit of the BMS concentrator were studied to determine the behaviour of the sphalerite, galena and chalcopyrite. The liberations and size distributions of the minerals were determined and the data were processed by the MATBAL 2 program to adjust the analysed values so that there would be a balance between amounts fed to and discharged from the flotation cells. A comparison of the results with similar data for samples collected in 1977 shows that sphalerite recovery was better from some cells and poorer from other cells. This suggests that monitoring the zinc content of the tailings from the cells would indicate when corrective steps need to be taken to maintain a constant recovery. It was also observed that large, free chalcopyrite grains were lost to the mill tailings as in 1977"--Abstract, page i.
