09-10-2017Wolframite, (Fe,Mn)WO4, is an iron manganese tungstate mineral that is the intermediate between ferberite (Fe2+ rich) and hbnerite (Mn2+ rich). Along with scheelite, the wolframite series are the most important tungsten ore minerals. Wolframite is found in quartz veins and pegmatites associated with granitic intrusives.

Sep 07, 2010The orebodies occur as veins. Wolframite and molybdenite are the dominant ore minerals. Two samples were selected for molybdenite Re-Os dating in order to elucidate the timing of mineralization. Re-Os datings of molybdenite from quartz-wolframite veins and disseminated in granite yield ages of 1537 Ma and 163.24.2 Ma respectively.

Abstract We present an analytical protocol for in situ U–Pb isotope dating of wolframite series minerals [ (Fe,Mn)WO 4 ], the main ore mineral for tungsten, by LA-SF-ICP-MS. Precision and accuracy of the protocol was intensively assessed using our newly developed well-characterized U–Pb wolframite reference material.

The nanocrystals were in monoclinic (wolframite structure) symmetry and possessed a band gap of 2.6 eV as shown by the XRD and optical measurements. The m-NiWO 4 exhibited much better photoelectrochemical H 2 O oxidation than TiO 2 and non-mesoporous NiWO 4 nanocrystals due to the enhanced crystallinity, surface morphology and mesoporosity.

Wolframite is iron – manganese tungstate (Fe,Mn)WO4, a solid solution of the two minerals ferberite (FeWO 4) and hbnerite (MnWO 4 ), while scheelite is calcium tungstate (CaWO 4 ). Other tungsten minerals range in their level of abundance from moderate to very rare, and have almost no economic value. Chemical compounds [ edit]
