Improving fine molybdenite flotation using a combination of aliphatic hydrocarbon oil and polycyclic aromatic hydrocarbon [PDF]
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,

International Journal of Mining Science and TechnologyA 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.

Adsorption Equilibrium and Mechanism and of Water Molecule on the Surfaces of Molybdenite (MoS2) Based on Kinetic Monte-Carlo Method [PDF]
Molecules, 2022 The oxidation/weathering of molybdenite (MoS2) is too slow to be monitored, even under pure oxygen and high temperatures, while it proceeds rapidly through humid air.

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

EFFECT of Pb2+ on the flotation of molybdenite in the presence of sulfide ion
Results in Physics, 2019 Although Na2S doesn’t depress the flotation of molybdenite, as the most utilized depressant, its effect on the flotation of molybdenite in the case where Pb2+ is involved has not been investigated yet.

Activation of peroxymonosulfate by natural molybdenite for the degradation of atrazine [PDF]
E3S Web of Conferences, 2020 In this work, molybdenite was used as a catalyst to activate peroxymonosulfate (PMS) for atrazine (ATZ) degradation. First, the effects of molybdenite dosage (0.05-0.30 g/L), PMS dosage (0.02-0.15 mM) and the initial pH (3.0-11.0) in the aqueous solution
