Selenium chemical element Britannica

Selenium (Se), a chemical element in the oxygen group (Group 16 [VIa] of the periodic table), closely allied in chemical and physical properties with the elements sulfur and tellurium. Selenium is rare, composing approximately 90 parts per billion of the crust of Earth. It is occasionally found

Selenium and Tellurium Statistics and Information usgs.gov

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 applications in rubber compounding, steel alloying, and selenium rectifiers. By 1970, selenium in rectifiers had largely been replaced by silicon, but its use

Smelting and Roasting Ores to recover gold, silver and

This is a concern because Arsenic is actually very common in many gold ores. Selenium, mercury and other toxic elements are also found in many high sulfide gold and silver ores as well. To roast sulfide ores, it takes a good red heat and a good amount of air, but not too hot as you don't want to melt them.
