(mineralogy)

CuO A triclinic mineral that occurs in small, shining, steel-gray scales, in black powder, or in black earthy masses; an ore of copper.

Tenorite

named for the Italian botanist M. Tenore, 1780–1861), a mineral of the oxide class, natural cupric oxide, CuO, containing 79.89 percent Cu.

Tenorite crystallizes in the monoclinic system. It occurs as concentrically botryoidal formations composed of minute lamellar crystals; dense grainy aggregates, known as melaconite, are sometimes found. Tenorite has a hardness of 3.5–1 on Mohs’ scale, and its density is 5,800–6,400 kg/m³. It is formed in the oxidation zone of copper deposits together with cuprite, malachite, chrysocolla, and native copper; less frequently it forms in volcanic sublimates. Tenorite forms no natural deposits and is extracted as a by-product with other copper minerals from the oxidation zone. It is a copper ore.
