    For example, the mineral realgar (AsS) is a sulfide which contains only the semimetal arsenic (As) and the nonmetal sulfur (S) In this case, the arsenic acts as a metal by donating electrons to the electronegative sulfur This type of compound is considered a semimetal sulfide; other examples are orpiment (As 2 S 3) and bismuthinite (Bi 2 S 3).

    Copper is enriched by processes during crystallisation of the granite and forms as chalcopyrite—a sulfide mineral, which is carried up with the granite Sometimes granites erupt to surface as volcanoes, and copper mineralisation forms during this phase when the granite and volcanic rocks cool via hydrothermal circulation.
