The Mineral Gallery - Sulfides Class
The Sulfide Class minerals comprise an economically important class of minerals. Most major ores of important metals such as copper, lead and silver are sulfides. Strong generalities exist in this class. The majority of sulfides are metallic, opaque, generally sectile, soft to average in hardness and they have high densities, black or dark-colored streaks, and an igneous origin.

mineral - Sulfide Minerals - The sulfides include the majority of ore minerals from which metals are obtained. Thus, lead sulfide forms the mineral galena; silver sulfide, argentite; and zinc sulfide, sphalerite. These minerals are often found together as ores.Two important sulfides of arsenic are realgar and orpiment. Antimony sulfide is called stibnite.
