·Drill cores from the Mittersill tungsten mine also called Felbertal were scanned with a drill core scanner using X ray computed tomography XCT and X ray fluorescence XRF Matrix amphiboles and quartz stand out as peaks in the XCT attenuation histogram whereas the main ore mineral scheelite has distinctly high attenuation Volumetric concentrations of the
The Watershed Project substantially adds to Tungsten Mining s global resource inventory and boasts a JORC 2012 Mineral Resource Estimate of grading % WO 3 comprising Measured Resources of at % WO 3 Indicated Resources of at % WO 3 and Inferred Resources of at % WO 3 at a cut off grade of % WO 3
·Market Report primary mine production of tungsten in 2010 totalled 97 000t WO 3 Tonnage wise this is less than the production of a single porphyry copper mine like Highland Valley in Canada which has also a feed grade similar or even lower than most tungsten mines Or if we look at

·During the study period domestic tungsten mine was the major tungsten resource in China with an amount of 1344 kt However nearly 23% of the total extraction was lost during the mining and beneficiation stages as the tailings Other tungsten losses occurred in the fabrication 24kt manufacturing 34kt and waste management 158kt stages
4 ·The Almonty Korea Tungsten project is the world s largest tungsten mine Discover its scope progress and its role in the tungsten sector The tungsten grade varies from ≥3% WO3 in the quartz mica alteration zone gradually decreasing to % WO3 in the amphibole zone through to % WO3 in the outer pyroxene garnet alteration zone
