• Sulfide mineral - Wikipedia

    en.wikipedia.org/wiki/Sulfide_minerals The sulfide minerals are a class of minerals containing sulfide (S 2−) or persulfide (S 2 2−) as the major anion.Some sulfide minerals are economically important as metal ores.The sulfide class also includes the selenides, the tellurides, the arsenides, the antimonides, the bismuthinides, the sulfarsenides and the sulfosalts. Sulfide minerals are inorganic compounds

    www.britannica.com/science/sulfide-mineral Sulfide mineral, any member of a group of compounds of sulfur with one or more metals. Most of the sulfides are simple structurally, exhibit high symmetry in their crystal forms, and have many of the properties of metals, including metallic luster and electrical conductivity.

The similar but rarer sulfarsenides are grouped here as well. Sulfide minerals consist of one or more metals combined with sulfur; sulfarsenides contain arsenic replacing some of the sulfur. Sulfides are generally opaque and exhibit distinguishing colours and streaks. (Streak is the colour of a mineral’s ...
  • The Mineral Gallery - Sulfides Class

    www.galleries.com/Sulfides 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.
