Copper-molybdenum ore beneficiation,flotation

In the copper-sulfur separation operation, due to the large amount of lime and the fine grinding particle size, it has a greater impact on the corresponding flotation of molybdenite; in the actual copper separation operation, the copper recovery rate is only ≤50 %. For some of these ores, the overall recovery rate is only 80% because of the relatively low grade of molybdenum in the original ore.

Copper-Molybdenum ores

Recovery of copper is by standard flotation reagents identified in the copper ore flotation description. Molybdenum will float naturally with the copper but can be crowded in the froth by the copper mineralization and use of a moly collector (such as diesel oil, kerosene, refined oils, pine oil or xanthate ester) enhances its floatability. Further, because optimum moly flotation pH is at 7-8 ...
