To extract about 2.2 pounds (1 kilogram) of tellurium requires the treatment of 1,000 tons of copper ore. Commercial-grade tellurium has a purity of 99.5% but higher grades of purity are also available. Producing a more refined grade of tellurium calls for yet another process. First, tellurium dioxide has to be dissolved in hydrochloric acid.Web
