Oxidation roasting of molybdenite concentrate

Transactions of Nonferrous Metals Society of China, 2015
In order to investigate the oxidation roasting of molybdenite concentrate in pure oxygen atmosphere, experiments at 673, 723, 773, 873 and 973 K were carried out. The phase transitions and morphology evolutions of the samples obtained at different temperatures after reacting for different time were analyzed by X-ray diffraction (XRD) and scanning ...

Onset of superconductivity in sodium and potassium intercalated molybdenum disulphide [PDF]

Molybdenum disulfide in the form of natural crystals or powder has been intercalated at -65 to -70 C with sodium and potassium using the liquid ammonia technique. All intercalated samples were found to show a superconducting transition.

A geochemical drainage survey of the Fleet granitic complex and its environs [PDF]

, 1978
A regional geochemical drainage reconnaissance programme was undertaken over 900 km2 of south-west Scotland centred on the Fleet granitic complex. Rocks of Ordovician and Silurian age outcrop over the area, into which have been intruded the Fleet and ...

Anomalous Lattice Vibrations of Single and Few-Layer MoS2

, 2010
Molybdenum disulfide (MoS2) of single and few-layer thickness was exfoliated on SiO2/Si substrate and characterized by Raman spectroscopy. The number of S-Mo-S layers of the samples was independently determined by contact-mode atomic-force microscopy ...

Molybdenite at Crown Point, Washington [PDF]

Geological Society of America Bulletin, 1904
Introduction The occurrence of molybdenite (MoS2) at Crown Point, Chelan county, Washington, is one of the most interesting in the United States for several reasons: First, because practically the entire commercial supply of the mineral in the United States for 1902 was mined at this locality. The amount is given by Dr J. H.
