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. For instance, gold-telluride ores could be classified into six mineral
