Sulfide

Sulfide is a chemical compound made when sulfur combines with other elements or compounds, often forming ions called sulfides. In nature and industry, sulfides are found in minerals like pyrite and are produced during processes such as metal smelting. They can also occur in the environment as byproducts of activities like oil refining. Chemically, sulfides can be toxic, giving off unpleasant odors like rotten eggs, and they play important roles in biological systems and geochemical cycles. Managing sulfides is essential to prevent environmental pollution and corrosion, especially in pipelines, wastewater treatment, and mineral processing.
