values from flotation of sample C shown in Table 4 and Figure 1 indicate that the flotation efficiency of Cu, Co and S was 100% at the pH values of 8.7 and 8.8. However, the flotation efficiency at pH 8.7 was better than pH of 8.8 because of high percent values of these elements in the concentrate phase. Therefore, flotation at pH of 8.7 was more
