Copper-Molybdenum ores Danafloat Home

Further, because optimum moly flotation pH is at 7-8 while optimum copper selectivity is typically in the 9-11 pH range, use of a moly collector in bulk flotation can improve floatability. Some mines find that the moly collectors can have a negative impact on copper flotation so testing and evaluation must be conducted to find the optimum moly collector hydrocarbon and frother products.

The molybdenum recovery from bulk copper-molybdenum concentrate might use the following method: Copper-molybdenum concentrate treatment with sodium sulfide. In this case, the copper sulfides and other sulfides are suppressed and the molybdenite could be recovered by flotation with non-polar (hydrocarbonic) collectors.
