Above all, the sulfides are the most important group of ore minerals because they are responsible for the concentration of a wide range of metals as mineable deposits. They are also potential sources of pollution, be it of the air, surface waters, or soils Mineralogy of Sulfides. INTRODUCTION. 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 Minerals - April 2004.
