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.

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, 1974An 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.

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 ...

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.

Metallurgical and Materials Transactions B, 2004
denite is also used as an important raw material of oxidization roasting for the preparation of ammonium molybdate in molybdenum industry [7,8] and as one of the main naturally metallic minerals associated with gold. [9] Furthermore, the extraction of nonferrous metals from sulfide ores belongs to the technically difficult and economically important ...

On rhenium content of molybdenite of Mount Mulat (Predazzo) and other Italian molybdenites
Geochimica et Cosmochimica Acta, 1963Abstract Determinations of rhenium content in some Italian molybdenites were made by a colorimetric method. It seems possible that the rhenium content may be correlated to the deposit formation temperature.

Electrical Properties of Molybdenite
Proceedings of the Physical Society. Section B, 1953The 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.

Reflectivity measurements on molybdenite
Economic Geology, 1966The spectral reflectivity of molybdenite was measured on an unpolished cleavage flake, a polished vertical section, and a polished basal section, both in air and in oil. From these measurements the refractive index and the absorption were calculated. Reflectivity peaks were found at 625 nm in air measurements and at 620 nm in oil measurements.

THE DETECTION OF VACANCIES IN MOLYBDENITE
Applied Physics Letters, 1967The etch-decoration method developed to detect lattice vacancies in graphite has been extended to the detection of lattice vacancies in molybdenite. Observations indicate that vacancies occur at sites from which a molybdenum atom is missing and that etch pits developed from these vacancies may be several layers deep; however, gold decoration can reveal
