selenium mining

Selenium mining involves extracting the element selenium from natural sources such as mineral deposits or as a byproduct of refining metals like copper and gold. It is not mined directly in large quantities but is recovered from ores or waste materials during processing. Selenium is used in electronics, glass manufacturing, and health products. The mining process includes locating selenium-rich deposits, extracting ore or waste materials, and processing them to isolate pure selenium through chemical and thermal methods. Proper environmental management is essential to prevent pollution, as selenium can be toxic in high concentrations.
