Molybdenite flotation in sea water was depressed in alkaline solutions when pH was higher than 9.0–9.5. At the same time, Cu recovery was only slightly reduced and was not significantly affected by pH.Copper-Molybdenum ores - Danafloat,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,
