Tungsten concentrations in Mittersill scheelite ore quantified with X-ray computed tomography

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 XCT high attenuation phase show an e...
