The main source of tellurium is from copper anode slimes, which contain precious metals as well as various tellurides. These slimes are roasted with sodium carbonate and oxygen to produce sodium tellurite. [1] Ag 2 Te + Na 2 CO 3 + O 2 → 2Ag + Na 2 TeO 3 + CO 2 (400–500 °C) This is a reaction with silver telluride.
