sulfide mineral Definition, Examples, Identification

The composition of the sulfide minerals can be expressed with the general chemical formula A m S n, in which A is a metal, S is sulfur, and m and n are integers, giving A 2 S, AS, A 3 S 4 and AS 2 stoichiometries. The metals that occur most commonly in sulfides are iron, copper, nickel, lead, cobalt, silver, and zinc, though about fifteen others enter sulfide structures.

Uses of Lead Lead Deposits and Resources

Lead commonly occurs in mineral deposits along with other base metals, such as copper and zinc. Lead deposits are broadly classified on the basis of how they are formed. Lead is produced mainly from three types of deposits: sedimentary exhalative (Sedex), Mississippi Valley type (MVT), and volcanogenic massive sulfide (VMS).
