Selenium and Tellurium Statistics and Information

Tellurium is a relatively rare element, in the same chemical family as oxygen, sulfur, selenium, and polonium: oxygen and sulfur are nonmetals, polonium is a metal, and selenium and tellurium are semiconductors (i.e., their electrical properties are between those of a metal and an insulator).

Selenium Prices, Occurrence, Extraction and Use

Selenium minerals such as Clausthalite and Naumannite are rare. Selenium, usually in the form of metal selenides, is the companion of sulphurous ores of the metals copper, lead, zinc, gold and iron. When these ores are roasted, the solid selenium dioxide in the fly ash or in the downstream sulfuric acid production collects as selenious acid.

Tellurium metal is chemically similar to selenium. Tellurium is more metallic and somewhat less toxic than this, but its compounds smell even worse. Tellurium metal probably has no biological role and has only very few, special applications. Tellurium metal can form nice crystals and sometimes natively occurs in nature, however it is very rare.
