Comparison of isotope data obtained with Sm-Nd and Re-Os methods for minerals and rocks from the Ozernoe ore occurrence, Salla-Kuolajarvi belt

Vestnik MGTU, 2021
Sm-Nd isochrone, drawn for rock-forming and sulfide minerals from the Ozernoe ore occurrence, indicates albitite age of 1,759 ± 11 Ma. It shows synchronous formation of albitite and sulfide mineralization, and fully corresponds to the earlier defined age

Incorporation of incompatible trace elements into molybdenite: Layered PbS precipitates within molybdenite

American Mineralogist, 2022
Abstract Trace elements in molybdenite can provide important information regarding the composition of ore-forming fluid and the evolution and genesis of ore deposits. However, the occurrence states and behavior of relatively incompatible trace elements (e.g., Pb and Os) in natural molybdenite remain ambiguous.

The possible existence of Hs in nature from a geochemical point of view [PDF]

, 2006
A hypothesis of the existence of a long-lived isotope 271Hs in natural molybdenites and osmirides is considered from a geochemical point of view. It is shown that the presence of Hs in these minerals can be explained only by making an additional ad hoc ...

Improving fine molybdenite flotation using a combination of aliphatic hydrocarbon oil and polycyclic aromatic hydrocarbon

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,
