Processing technologies for gold-telluride ores

2016-9-12 · It was well known that gold was commonly associated with tellurium minerals. The cooccurrence of tellurium with noble metals such as gold and silver was attributed to the semi-metallic nature of tellurium. The composition varied significantly from different tellurium minerals.
