Locked-Circuit Tests
Based on the recommended flotation conditions, the
locked-circuit tests of bulk flotation were conducted using
the flowchart and reagent scheme given in Figure 10. The
results of locked-circuit test are shown in Table 2.
As seen from Table 2, the results demonstrate that
BK386 exhibits good adaptability to this ore sample. It
enables the production of a bulk concentrate with a Cu
grade of 28.95%, Cu recovery rate of 90.33%, Mo grade of
0.15%, and Mo recovery rate of 72.7%, thereby achieving
