do you know a mineral of molybdenum with unacceptable floatability? molybdenum is a valuable mineral which could be found in porphyry copper deposits and molybdenum is the main mineral of molybdenite. according to our recent studies we have observed a new mineral of molybdenum with different float-a
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.
this molybdenum flotation circuit, based on 250-500 tons per 24 hours is designed for low-grade molybdenum ore having high-grade streaks and with pyrite-quartz gangue.it is also basically sound for many other friable sulphide ores, such as antimony, silver and even some lead ores. the basic ideas stressed in this moly flotation flowsheet are the importance of simplicity and the quick removal
there are several flow sheets (listed in fig. 1a and b) used in the flotation recovery of copper and molybdenum from their porphyry sulfide ores. fig. 1a is a typical flow sheet that consists of two stages (raghavan and hsu, 1984, bulatovic, 2007, liu et al., 2011).the first stage, commonly known as the copper circuit, produces a bulk copper sulfide molybdenum sulfide concentrate.
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.
