... 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...

... ; Liu et al., 2020 ). Tellurium concentration in the gold ores is typically in the range of tens to hundreds of parts per million, with estimated tellurium resources in excess of 1,000 t ( Luan et al., 1985 , 1991 ; Jian et al., 2014 ). The S60 gold-bearing quartz vein, with estimated gold...

.... 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...

.... 10E, F ). Native bismuth 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...

... 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...

... (Ontario, Canada), see ( www.mndm.gov.on.ca/sites/default/files/2017_ geo_labs_brochure.pdf ). 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...

... Forests classifier was refined to not include Au. Tellurium, however, was not omitted from this classifier despite the lack of Te data from SEDEX deposits. The classifier has difficulty identifying orogenic Au mineralization because Te is commonly associated with Au mineralization ( Belousov et al., 2016...

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...

... a likely magmatic contribution to the mineralized fluid (Cooke and McPhail, 2001 ). Selenium is a highly chalcophile element and substitutes readily for sulfur in sulfide minerals (Simon et al. , 1997 ). Tellurium is less compatible in sulfides than Se due to the greater atomic radius of the telluride...
