The floatability of molybdenum during copper flotation also depends on many factors, including type of collector, type of frother, flotation pH and type of hydrocarbon oil used. During the flotation of copper molybdenum ores, fuel oil or kerosene is added to the grinding to enhance molybdenum recovery.

Copper production About 80 % of primary copper production comes from lowgrade or poor sulfide ores. After enrichment steps, the copper concentrates are usually treated by pyrometallurgical methods. Generally, copper extraction follows the sequence (see Figure below): 1. Beneficiation by froth flotation of ore to give copper concentrate

Arsenic minerals pose a problem for copper flotation concentrates since they are often associated with copper minerals, display similar flotation behaviour to copper minerals and therefore report to final copper flotation products. Despite extensive research, the rejection of arsenic minerals in copper flotation is still a challenge.
