Molybdenum Flotation - Froth Flotation (Sulphide & Oxide ...

Molybdenite is naturally floating and there should not be any problem in recovery. In copper moly bulk floatation circuit more than 80% of the moly reports with copper concentrate. But in many ores there are graphitic/carbonaceous material which causes enormous problem in achieving desired product moly grade. Colour wise they both look similar.
