Effects of solution pH and polyethylene oxide concentrations on molybdenite–molybdenite, molybdenite–kaolinite, and molybdenite–quartz interaction forces: AFM colloidal probe study

Separation and Purification Technology, 2022
Abstract Molybdenite (MoS2), a major resource for Mo, is often associated with some gangue minerals, such as kaolinite and quartz. The flotation separation of fine-grained molybdenite from gangue minerals is always difficult due to the low efficiency of capturing fine particle by bubbles and the heterogeneous agglomeration with gangue particles.

Granite molybdenite systems

Economic Geology, 1981
Stockwork molybdenite deposits in the western conterminous United States may be divided into two groups based on the chemistry of the source pluton: granodiorite systems and granite systems. These two groups show significant differences in age, tectonic setting at time of formation, and orebody geometry.Granite molybdenite systems develop in, and ...

Bioleaching of molybdenite

Hydrometallurgy, 2008
Abstract Molybdenum was bioleached from molybdenite-containing mine waste samples and from high purity molybdenite in solutions amended with ferrous sulfate. Bioleaching of Mo occurred when solution Eh exceeded 750 mV to 800 mV (s.h.e.). The rate of bioleaching of high purity molybdenite increased with decreasing particle size, averaging 3.22 mg Mo/m

Dislocation etching in molybdenite

Journal of Materials Science, 1974
An etchant to reveal the non-basal dislocations on the (0001) faces of MoS2 single crystals has been established. Evidence concerning the ability of this etchant to reveal the sites of non-basal screw dislocations is also given.

Electrical Properties of Molybdenite

Proceedings of the Physical Society. Section B, 1953
The following electrical properties of natural crystals of MoS2 have been measured: conductivity, Hall coefficient and thermoelectric power over the temperature range - 183°C to 500°C, and the room temperature change of conductivity in a magnetic field. It was found that the majority of the specimens were p-type semiconductors.

Molybdenite flotation /

2010
Thesis (PhD)--University of South Australia, 2010. The low flotation recovery of fine and coarse molybdenite particles is one of the major issues in the flotation process of molybdenite-bearing copper sulfide ores. In this study, the flotation behaviour of fine and coarse molybdenite particles was investigated as a function of particle size, edge to ...

Dislocations in Molybdenite

Journal of Applied Physics, 1965
The formation of the different types of dislocations in molybdenite is discussed. An interpretation based on the occurrence of growth faults in natural crystals is advanced which explains the existence of dissociated and undissociated dislocations.
