…Tellurium occurs rarely as the elemental mineral tellurium, but is more commonly found as a compound of gold, silver, copper, lead, iron, and bismuth, and is found in a wide variety of minerals. The main types include sylvanite (AuAgTe 4 ) , calaverite (AuTe 2 ) , krennerite (AuTe 2 ) , petzite (AuAg 3 Te 2 ) , hessite (Ag 2 Te), tetradymite (Bi 2 Te 2 S), altaite (PbTe), coloradoite (HgTe), rickardite (Cu 4 Te 3 ), and the oxide mineral tellurite (TeO 2 ). The so-called tellurium gold ores, which are important as gold ores, are composed of silver-bearing gold telluride minerals such as calaverite, krennelite, and needle tellurite, and occur in shallow to mesothermal gold-silver veins together with native gold and other silver minerals.
