2020-1-17  Tellurium (Te) is a p-type semiconductor with a narrow band-gap of 0.34 eV [1,2,3].Due to its highly anisotropic crystal structure, Te shows many unique properties including photoconduction, piezoelectricity, and thermo-electric effect [1, 4,5,6].Te is primarily used in the production of cadmium telluride (CdTe) for CdTe thin-film solar cells, one of the most common types of solar panels ...

Treatment of gold-telluride ores - ScienceDirect

2005-1-1  Yan and Hariyasa (1996) also examined the flotation performance of a high-grade tellurium gold ore from the Kalgoorlie deposit. They showed that tellurides float readily at natural pH values (∼8.0) with the addition of frother only, and that the recovery and rate of flotation could be improved by the addition of xanthates or mercaptobenzothiazol.

Treatment of Gold–Telluride Ores - ScienceDirect

2016-1-1  Dziurdzak et al. (1989) investigated the pressure oxidation of flotation concentrate obtained from Kalgoorlie gold–telluride ores. The untreated concentrate, which contained 79 g/t gold, gave ∼68% gold extraction by simple cyanidation. About 40% of the refractory gold was combined with tellurium, and the balance was locked in sulfides.

Effect of Tellurium on Brass

2017-2-4  The results of these experiments show that the amount of tellurium usually contained in refined copper does not appreciably affect the rolling properties of high-brass. If, however, the copper contains over 0.10 per cent, (giving about 0.06 per cent, in the brass), the metal manifests a tendency to crack in the rolling.
