Abstract Rhenium, Os, and Pt are redox sensitive elements that concentrated in highly reducing environments such as those associated with black shales but mobile under more oxidizing conditions arc volcanism. They chalcophile many terrestrial ore-forming environments, their isotopic systematics provide unique opportunities to date the formation of sulfide ore deposits understand petrogenesis. F...

The Tuwu–Yandong belt contains five porphyry Cu deposits (Fuxing, Yandong, Tuwu, Linglong, and Chihu), constituting the largest metallogenic in Northwest China. However, framework for remains controversial. Rhenium-osmium dating of molybdenite from Chihu comparisons with previous geochronological data suggest that two episodes (335–330 Ma 323–315 Ma) Cu–Mo mineralization occurred belt, metals w...

bioleaching, molybdenum disulfide, catalyst residue Molybdenum disulfide, MoSz, is used as a catalyst in coal-oil coprocessing. For most processes using molybdenum catalysts to be economical, the molybdenum must be recovered and recycled. Chemical recovery schemes have been devised, but typically recover only a fraction of the molybdenum. There are reports in the literature that bacteria can ox...

In the present study, we collected and investigated spinels from Man Sin deposit in Myanmar using standard gemological testing, microscopic observation, EDXRF, Raman spectrometry. The color observation was performed under various lighting conditions to show differences. A very high Cr/Fe ratio is linked with exceptionally strong red fluorescence. Microscopic spectroscopy identified mineral incl...

Continuous counter-current extraction of rhenium from roasting dust leach liquor was carried out using a mixer-settler extractor. Tributylphosphate was used as the extractant diluted in kerosene. The effects of the flow rates and extraction stages number were investigated. The extraction efficiency was affected by the flow rates of the aqueous and organic phases, and its mechanism was qualitati...
