Introduction to Mineral Processing

The concentrate, which is now approximately 30% Cu and % Mo, is pumped to the molybdenum plant where the molybdenum disulfide is separated from the copper sulfide. Chemicals referred to as depressants are added to the pulp to reduce the flotation of the copper minerals while allowing the molybdenum minerals to float.

Low Molybdenum Recovery in Bulk CopperMoly Flotation Circuit

In a flotation locked cycle test, a poor/low moly recovery was obtained at % as it appeared that molybdenum had not reached equilibrium. The calculated head grade trend, shown in Figure 828 indicates that the moly and most of the other elements had not reached convergence when the test was terminated. Figure 829 shows the trend in recoveries as the cycles were executed.

The milled ore/gangue powder is mixed with a liquid and aerated in the flotation step. The less dense ore rises in the froth to be collected, while the gangue sinks to be discarded. Flotation separates the metallic minerals from the gangue this way and – in the case of copper/ molybdenum ores – separates molybdenite from copper sulphide.
