tet·ra·he·drite

 (tĕt′rə-hē′drīt′)
n.
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.]

tetrahedrite

(ˌtɛtrəˈhiːdraɪt)
n
(Minerals) a grey metallic mineral consisting of a sulphide of copper, iron, and antimony, often in the form of tetrahedral crystals: it is a source of copper. Formula: (Cu,Fe)12Sb4S13

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]
