zincite

zinc·ite

Z0016700 (zĭng′kīt′)n. A red to yellow-orange zinc ore, ZnO.

zincite

(ˈzɪŋkaɪt) n (Minerals) a red or yellow mineral consisting of zinc oxide in hexagonal crystalline form. It occurs in metamorphosed limestone. Formula: ZnO

zinc•ite

(ˈzɪŋ kaɪt)

n. a brittle, deep red to orange-yellow mineral, zinc oxide, ZnO, having a crystalline or granular form: formerly an important ore of zinc. [1850–55]

zincite

[′ziŋ‚kīt] (mineralogy) (Zn,Mn)O A deep-red to orange-yellow brittle mineral; an ore of zinc. Also known as red oxide of zinc; red zinc ore; ruby zinc; spartalite.

Zincite

a mineral of the class of simple oxides. Zincite, with the chemical composition ZnO, usually contains admixtures of MgO (up to 9 percent), PbO (up to 5.3 percent), and FeO (up to 1.1 percent). It crystallizes in the hexagonal system. It usually occurs in the form of granular aggregates; zincite crystals are rare. The color ranges from orange-yellow to dark red. The hardness on Mohs’ scale is 4–5, and the density is 5,640–5,680 kg/m³. A semiconductor, zincite is found in recrystallized limestones of contact metasomatic deposits, in which it is associated with willemite, franklinite, and other rare minerals. Zincite is mined in the USA, at Franklin, N.J., as a zinc ore. It has also been discovered in several lead-zinc deposits.
