Molybdenite is the world's principal source of rhenium (Re), a critical element in multiple high-tech applications. However, the Re contents in molybdenite vary by orders of magnitude on scales ranging from single grains to whole deposits. In order to better understand the systematics of this variation and what geochemical factors control …

Molybdenite is the most important mineral resource for molybdenum, and it can be recovered as a byproduct from porphyry copper ores. Froth flotation, which is the most cost-effective way to separate Mo and Cu in industry, has been studied extensively. Previous research showed that the mineralogy of molybdenite could be different from …

Molybdenite is a very soft metallic mineral. It can be easily confused with graphite, but not with many other minerals. Graphite has a darker black-silver color and a black-gray to brown-gray streak, whereas molybdenite has a bluish-silver color and streak. Unfortunately, the difference is so slight that it is recommended that the two minerals be …
