Tetrahedrite is a 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.
