Copper Molybdenum Ores Depressant D461 Use In Floatation Process . Application: Copper Depressant D461 is a highly effective and essential flotation depressant. It is used in the flotation process of copper-molybdenum ores.
Flotation is the most widely used method for molybdenum ore processing. It relies on the differences in the surface properties of molybdenite and other minerals present in the ore.
Typically, rougher molybdenite flotation and recovery from bulk copper/molybdenum concentrates involves the use of alkalisulfides, Nokes reagents, cyanides, oxidants, and/or thermal treatment to depress copper sulfide minerals. The bulk copper/molybdenum feed generally varies from 0.2% Mo to 1.0% Mo, and with traditional reagents the single-stage rougher flotation recovery of …

Many different types of flotation cells are used in modern moly plants, and each type of flotation cell has its own unique advantages suited for particular ore and process conditions.
An effective flotation approach is proposed for improving the recovery of molybdenite fines from a finely-disseminated molybdenum ore. To maximize the flotation recovery of molybdenum, process mineralogy of raw ore, contrast tests, optimization of operation conditions and particle size analysis were systematically investigated. Process mineralogy …
