Selenium toxicity in sheep grazing reclaimed phosphate mining sites

Phosphate mining operations in southeastern Idaho have exposed selenium (Se) that was originally sequestered in the subsurface. Sheep grazing in these areas have died as a result of high Se concentrations in forage and water. This study was designed to monitor

Mineral Resource of the Month: Selenium

 · Selenium, a relatively rare element with diverse uses, is widely distributed within Earth''s crust, but it does not occur in concentrations high enough to justify mining solely for its recovery. Selenium is recovered as a byproduct of nonferrous metal ore processing, principally from the anode slimes associated with electrolytic refining of copper.
