tet·ra·he·drite

(tĕt′rə-hē′drīt′)

A grayish-black mineral, essentially (CuFe)₁₂Sb₄S₁₃, often containing other elements, and used as an ore of copper.

[German Tetraëdrit, from Greek tetraedros, four-faced (from its four-faced crystals); see tetrahedron.]

tet•ra•he•drite

(ˌtɛ trəˈhi draɪt)

n.

1. any of a group of copper and silver ore minerals ranging from copper-iron antimony sulfide to copper-iron arsenic sulfide; copper is the chief metal but other metals (Fe, Zn, Ag) substitute for it extensively.

2. the copper-iron antimony sulfide, (Cu, Fe)₁₂ Sb₄S₁₃, end member of the group.

[1865–70; < German Tetraëdrit (1845); see tetrahedron, -ite¹]
