A sulfide mineral of iron, copper and arsenic that is an ore of copper
a blackish lead-gray mineral, closely related to tetrahedrite. It is essentially a sulphide of arsenic and copper
Tennantite is a copper arsenic sulfosalt mineral. Its chemical formula is Cu12As4S13. It is grey-black, steel-gray, iron-gray or black in color. A closely related mineral, tetrahedrite has antimony substituting for arsenic and the two form a solid solution series. The two have very similar properties and is often difficult to distinguish between tennantite and tetrahedrite. Iron, zinc, and silver substitute up to about 15% for the copper site. The mineral was first described for an occurrence in Cornwall, England in 1819 and named after the English chemist Smithson Tennant. It is found in hydrothermal veins and contact metamorphic deposits in association with other Cu–Pb–Zn–Ag sulfides and sulfosalts, pyrite, calcite, dolomite, siderite, barite, fluorite and quartz.
