Wolframite in-situ U-Pb dating by LA-ICP-MS can constrain the W metallogenic age directly and accurately. In this study, homogeneous BSE images and stable trace element compositions of wolframite indicate that it formed in one generation and with no intense post-transformation subjection (Fig. 11 c, d, and 13). Our in-situ U …

Wolframite crystals from the two deposits display two generations (Fig. 2 e–h), indicating that the early wolframite (Wol-1) could have been altered by the late wolframite (Wol-2). This process may redistribute U and Pb in Wol-1, causing complete or partial resetting of the U–Pb isotope system in wolframite ( Harlaux et al., 2018a ).

The wolframite sample was naturally co-doped with Mn and Fe, which both showed the feature of FeWO 4 and MnWO 4 in infrared spectroscopy. Compared with the two end-members, natural wolframite exhibited narrower bandgap and enhanced visible-light absorption. Moreover, natural wolframite was found to successfully degrade …

Wolframite occurs mainly as radial plate column and have a length of 2–4 cm. It is noteworthy that wolframite crystals distributed at the edge of the vein contribute almost all the great economic significance ore minerals, accompanied by a small amount of scheelite. Contrary to the YLA section, the scheelite in the wolframite quartz veins ...

Tungsten, abbreviated as W on the periodic table, is a rare and valuable metal known for its exceptional physical and chemical properties. Tungsten ore refers to the natural rock or mineral containing tungsten in its compound form. Tungsten is commonly found in nature in the form of tungstates, such as scheelite (CaWO4) and wolframite …

Extraction of tungsten from wolframite ore (Fe, Mn)WO 4 was achieved using ammonium phosphate salt as flux. The supplied ore was predominantly composed of iron-rich endmember called ferberite (FeWO 4) and other minor phases identified as quartz and elsmoreite.Fusion of the wolframite ore sample (ratio 1:25) yielded an unstable …
