...Nicole C. Hurtig; Alexander P. Gysi; Thomas Monecke; Sven Petersen; Mark D. Hannington Abstract Volcanogenic massive sulfide deposits may represent a significant future source of Te, which is a critical element important for the green energy transition. Tellurium is enriched in these settings by up...

... the minerals industry with enhanced opportunities to secure the additional supply of associated or potential by-product elements. These include tellurium, selenium, bismuth, and antimony (among others), some of which are already predominantly produced as by-products from copper anode slimes. This study...

... tellurides is one of the suite of metallic minerals that often accompany gold mineralisation and formed under lower temperature conditions (~390 C) associated with quartz veins and massive sulphides that have significant enrichment in Au (Gunter, 2019). Significant enrichment of bismuth and tellurium...

... concordant with the host-rock foliations. The gold-bearing quartz veins have a pronounced Te signature, with a wide variety of tellurides reported ( Bi et al., 2011b ; Jian et al., 2014 , 2015 , 2020 ; Liu et al., 2020 ). Tellurium concentration in the gold ores is typically in the range of tens...

.... Tellurium-bearing minerals commonly form isolated euhedral to subhedral grains or composite grains (up to 525 μm in size) of Ag-, Bi-, Pb-, and Au-rich tellurium-bearing minerals ( e.g ., hessite, tellurobismuthite, volynskite, altaite, and petzite). Panchromatic cathodoluminescence imaging revealed four...

... is frequently observed as ovoidal inclusions within bismuthinite ( Figs. 10F and 11C ). Xenomorphic hedleyite (Bi 7 Te 3 ) is the main tellurium mineral, always closely associated with the bismuthinite and native bismuth. Tetrahedrite [(Cu,Fe) 12 Sb 4 S 13 ] and a bismuth-antimony-sulfide, close...

... lingbaoite grain is about 30 × 12 μm in size. At least two stages of gold and telluride mineralization are recognized in the lingbaoite-bearing sample set. The first stage is characterized by the deposition of lingbaoite, native tellurium, and sylvanite, within the commonly observed mineral assemblages...

The concentrations of the major elements (as well as Cu, Ni, and Co) were obtained according to a standard XRF analysis. Gold, silver, selenium, and tellurium were determined by an ultra-trace ICP-MS method...

Tellurium, however, was not omitted from this classifier despite the lack of Te data from SEDEX deposits. The classifier has difficulty...

Tlapallite is only the second naturally occurring compound containing tellurium in both the 4 + and 6 + oxidation states with a known crystal structure, the other being carlfriesite, CaTe 4+ 2 Te 6+ O 8 . Carlfriesite is the predominant secondary...

..., 2 to 340 ppm Ag, 2 to 770 ppb Au, and 0.2 to 1000 ppm Cl. Tellurium abundances are highly variable within sulfides, which is likely due to the presence of telluride micro- or nano-phases. Based on morphology, composition, and the absence of monosulfide solid solution, the sulfides are interpreted...

On the northern edge of the Panzhihua–Xichang region, a solitary tellurium deposit has been discovered in Shimian County (102°11′06″ E, 29°10′27″ N). It is a sulfide deposit with tetradymite as the main Te mineral, which indicates a sulfide deposit...
