The microbial adaption enhanced the Au–Ag–Te contents in biological leaching of telluriumbearing ore minerals. This suggests that bioleaching with adapted microbes can be used both as a pretreatment and in the main recovery processes of valuable metals.

The paragenesis of native metals (gold, silver, tellurium and rhenium), tellurides and sulfosalts was formed at the latest stage of the hydrothermal processes, at 165–190°C. Keywords: massive sulfide ore, gold, silver, platinumgroup elements, Uzelginsk deposit, Southern Urals, Russia.

Copper(I) sulfide is a copper sulfide, a chemical compound of copper and sulfur. It has the chemical compound CuS. ... There are two forms of CuS: a low temperature monoclinic form ("lowchalcocite") which has a complex structure with 96 copper atoms in the unit cell [7] ...
