The influence of Ca2+ and pH on the interaction between PAHs and molybdenite edges
, 2017 Nonpolar hydrocarbon oils are widely used as collectors for floating molybdenite. However, they can only adsorb on molybdenite faces and not on molybdenite edges, resulting in limited molybdenite recovery, especially in processed water containing a high ...

Effect of Sodium Sulfite on Floatability of Chalcopyrite and Molybdenite
, 2018 Sodium hydrogen sulfide (NaHS) is commonly used as a copper depressant in the selective flotation of copper and molybdenum ores. However, the process is facing health and safety issues because NaHS readily yields toxic hydrogen sulfide gas (H2S) under ...

Molybdenite occurrences in Greece: mineralogy, geochemistry and depositional environment
, 2010 Molybdenite occurs mainly in three mineralization types in Greece: (a) porphyry Mo-Cu-(±Te-Ag-Au), (b) reduced intrusion-related Mo-W systems (skarn, intrusion-hosted) and (c) shear zone-related Cu-Au-Bi-Mo. In porphyry-Mo-Cu prospects the molybdenite is

Optimization on molybdenite flotation
, 1987 Concn. of low-grade molybdenite ore was carried out by bulk flotation of Cu and Mo sulfides after ascertaining the theor. liberation particle size at 100 mesh. Statistically designed expts. were carried out using variables of (1) K Et xanthate collector

Multiple age components in individual molybdenite grains
, 2016 Re-Os geochronology of fractions composed of unsized, coarse, and fine molybdenite from a pod of unusual monazite-xenotime gneiss within a granulite facies paragneiss, Hudson Highlands, NY, yielded dates of 950.5 ± 2.5, 953.8 ± 2.6, and 941.2 ± 2.6 ...

Reactivity of a molybdenite concentrate against chemical or bacterial attack
, 2001 A study is made on the reactivity of a molybdenite concentrate (46.7% Mo) in response to chemical attack, using HNO3, H2SO4 of mixtures or both acids, or to attack by bacteria (mesophiles and moderate or extreme thermophiles).
