  • Argentiferous tetrahedrite is also abundant with a generally high silver content.
  • Silver was also produced from ores including tetrahedrite, stephanite, and pyrargyrite.
  • Also present are veins along aplitic intrusions containing argentiferous galena and tetrahedrite with bornite.
  • These deposits only rarely contain cinnabar or tetrahedrite.
  • The three main ore-bearing minerals are argentiferous galena, sphalerite, and argentiferous tetrahedrite.

Encyclopedia Article for tetrahedrite

common sulfosalt mineral, an antimony sulfide of copper, iron, zinc, and silver [(Cu,Fe,Zn,Ag)12Sb4S13], that is an important ore of copper and sometimes of silver. It forms gray to black metallic crystals or masses in metalliferous hydrothermal veins. Tetrahedrite forms a solid solution series with the similar mineral tennantite, in which arsenic replaces antimony in the molecular structure. It is found in important quantities in Switzerland, Germany, Romania, the Czech Republic, France, Peru, and Chile, and both minerals occur in large amounts in Colorado, Idaho, and other localities in the western United States. For detailed physical properties, see sulfosalt (table)
