Improving fine molybdenite flotation using a combination of aliphatic hydrocarbon oil and polycyclic aromatic hydrocarbon

Results in Physics, 2019
Kerosene is widely used as a collector in molybdenite flotation. However, it can only adsorb on molybdenite faces but not on molybdenite edges, which is unfavorable for the flotation of fine molybdenite particles with high edge/face ratios. In this study,

A novel molybdenite depressant for efficient selective flotation separation of chalcopyrite and molybdenite

International Journal of Mining Science and Technology
A novel small molecule depressant (M-DEP) was used to separate chalcopyrite and molybdenite via flotation. The results showed that M-DEP had an excellent selective depression on molybdenite, while had little effect on the flotation of chalcopyrite.

Using pectin to separate talc and molybdenite through the surface modification with Cu2+: Applications and mechanism

International Journal of Mining Science and Technology, 2023
Organic depressants have low selectivity in separating molybdenite and talc because their metal sites lack activity for organics chemisorption. In this study, surface modification by copper sulfate was used to induce the differential adsorption of pectin

The study of molybdenite types related to the ore processing plant of the Sar Cheshmeh mine

Journal of Economic Geology, 2011
Molybdenite occurs in five forms in the Sar Cheshmeh porphyry copper deposit, namely, (1)-veinlets with quartz-molybdenite, (2)-veinlets with quartz-molydenite that were filled with pyrite, (3)-veinlets with quartz-molybdenite-pyrite–chalcopyrite, (4 ...
