Mineralogy of Sulfides | Elements | GeoScienceWorld

 · Sulfide minerals are compounds in which sulfur is combined as an anion with a metal (or semi-metal) cation or cations. The definition is commonly widened to include minerals in which the anion is As or Sb, sometimes together with S, and to include Se and Te minerals. The sulfosalts are a special group of the sulfide minerals that have a general ...
