Sulfides present in aqueous solution are responsible for stress corrosion cracking (SCC) of steel, and is also known as sulfide stress cracking. Corrosion is a major concern in many industrial installations processing sulfides: sulfide ore mills, deep oil wells, pipelines transporting soured oil, Kraft paper factories.

Copper is found in nature mainly in oxide and sulfide ores. The oxide ores are processed via hydrometallurgical routes because they are easily dissolved in acid. Conversely, sulfide ores are practically insoluble in acid and must undergo pyrometallurgical routes [ 40 ]. Table 1 shows the main copper minerals found in nature [ 40, 53, 54, 55 ].
