Froth flotation is widely used for concentration of base metal sulphide minerals in complex ores. One of the major challenges faced by flotation of these ores is selection of the type of flotation reagents. In this study, the D-optimal experimental design method was applied to determine the optimum conditions for flotation of copper and molybdenum in the rougher …
· Fig. 1, Fig. 2 show flotation results obtained with two different chalcopyritic Cu–Mo ore samples floated in fresh water and sea water. Molybdenite flotation in sea water was depressed in alkaline solutions when pH was higher than 9.0–9.5. At the same time, …
· A molybdenum (Mo) concentrate assaying 6.00% copper (Cu) and 19.01% Mo was magnetically sorted using a diamond-shaped steel rod medium mesh at a feed concentration of 20% and a pulp flow rate of 5 L/min from a Cu-Mo flotation concentrate with 88% of particles smaller than 23 μm using the separator.
· Flotation separation of chalcopyrite from molybdenite was studied using seaweed glue (SEG) as a depressant. Flotation process and mechanism were examined by response surface methodology, flotation tests, adsorption tests, zeta potential measurements and fourier transform infrared (FT-IR) spectra. Response surface …
· The separation of both hydrophobic chalcopyrite and molybdenite represents a major problem in the treatment of copper–molybdenum sulfide ore. Both of them easily lead to flotation concentrates, thus reducing concentrate grade and causing downstream processing problems as well as increased smelting costs [ 2 ].

· Copper and molybdenum flotation process is commonly used for copper and molybdenum ore with pretty high grade, while it's rarely adopted in industrial production. In part combined flotation process, molybdenum with high floatability will be concentrated first, and then copper and molybdenum combined concentrate are concentrated together.
The main collective copper-molybdenum flotation was performed for 17 minutes, the control one for 8 minutes, and in the basic mode the following reagents were used as a …
