Low Molybdenum Recovery in Bulk Copper-Moly Flotation Circuit

In a flotation locked cycle test, a poor/low moly recovery was obtained at 47.3% as it appeared that molybdenum had not reached equilibrium. The calculated head grade trend, shown in Figure 8-28 indicates that the moly and most of the other elements had not reached convergence when the test was terminated. Figure 8-29 shows the trend in recoveries as the cycles were executed. Moly recoveries ...
