Dissecting the Re-Os molybdenite geochronometer [PDF]
AbstractRhenium and osmium isotopes have been used for decades to date the formation of molybdenite (MoS2), a common mineral in ore deposits and the world’s main source of molybdenum and rhenium. Understanding the distribution of parent 187Re and radiogenic daughter 187Os isotopes in molybdenite is critical in interpreting isotopic measurements because

EFFECT of Pb2+ on the flotation of molybdenite in the presence of sulfide ion
Although Na2S doesn’t depress the flotation of molybdenite, as the most utilized depressant, its effect on the flotation of molybdenite in the case where Pb2+ is involved has not been investigated yet.

Selective Leaching of Molybdenum from Bulk Concentrate by Electro-Oxidation
This paper proposes selective leaching of molybdenum from Mo/Cu complex bulk concentrates in a 5 M NaCl solution using the electro-oxidation method. Here, the effects of several factors such as pH, pulp density, current density, and temperatures were ...

Study on Process Mineralogy and Mineral Processing Technology of A Low Grade Copper-Molybdenum Ore
A copper-molybdenum ore in Qinghai contains 0.084% Mo and 0.067% Cu. Process mineralogical study shows that molybdenum in the ore mainly exists in the form of molybdenite, while copper in the form of chalcopyrite, chalcocite and bornite.
