BORNIT

BORNIT, mineral, formulai kimiyoiash Su5FeS4. Ba iftikhori mineralshinosi chekh I. Born nomguzori shuda­ast. Du modifikatsiyai polimorfi: balandaharorat (az 228°S baland) – silsilai bulurbandiash kubi-geksaoktaedri va pastharorat (az 228°S past) – silsilai bulurbandiash tetragonali-skalenoedri dorad. Beshtar dar shakli jinshoi zichi donador va zarraho vomekhurad. Rangash tirai surkhtob. Jiloyash filizzi, sakhtiash 3 – 3,5, zichiash 4900 – 5300 kg/m³. Dar kislotai nitrat (NNO₃) hal meshavad. Tarkibi kimiyoiash doimi nest. Az ruyi formulai kimiyoi boyad chunin boshad: Su – 63,3 %, Fe – 11,2 %, S – 25,5 %. Ammo tarkibi Bornit dar hududhoi kalon tagyir meyobad, zero tarkibash mahluli sakhti khalkoperit va khalkozin doshta metavonad. Dar raghoi hidrotermali hamrohi khalkozin, galenit, ofalerit, pirit duchor meoyad. Dar natijai oksidshavi az Bornit mineralhoi malakhit, azurit, kuprit va gayra hosil meshavand. Dar tabiat ba miqdori nisbatan kam mavjud buda, madani muhimmi mis ast. Bornit dar konhoi Russiya, Qazoqiston, IMA, Sloveniya, Polsha va Namibiya duchor meshavad.
