Selenium and Tellurium Statistics and Information

Selenium and Tellurium Statistics and Information. Commercial quantities of selenium are recovered as a byproduct of the electrolytic refining of copper where it accumulates in anode residues. Growth in consumption was driven by the development of new uses, including appli ions in rubber compounding, steel alloying, and selenium rectifiers.

the demand for its parent metal, copper. Tellurium is typically extracted from copper refined by an electrolytic process, which is a cost effective technique applied to highgrade copper ores. In this process, tellurium and other impurities, such as gold, silver, and platinum, are concentrated onto, and then removed from, crude copper anodes.
