tetrahedrite

tet·ra·he·drite

T0131900 (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]

tetrahedrite

[‚te·trə′hē‚drīt] (mineralogy) (Cu,Fe,Zn,Ag)₁₂Sb₄S₁₃ A grayish-black mineral crystallizing in the isometric system as tetrahedrons and occurring in massive or granular form; luster is metallic, hardness is 3.5-4 on Mohs scale, and specific gravity is 4.6-5.1; an important ore of copper. Also known as fahlore; gray copper ore; panabase; stylotypite.
