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.
