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.
