The main source is sludge from electrolytic refining of copper and lead. The sludge is calcined, tellurium remains in the cinder, which is washed with hydrochloric acid. Tellurium is extracted from the resulting hydrochloric acid solution by passing SO2.
Use of
Used in alloys with lead in the manufacture of lead-acid batteries, battery plate current conductors, cable sheaths. Production of X-ray and gamma ray detectorsCdZnTe alloy.
