摘要
包头白云鄂博主东矿中贫氧化矿中铌有很大的回收价值,本文探讨了主要铌矿物的特点及选矿性质,认为弱磁—强磁是初步富集铌的有效途径。本文还较为详细地介绍了从强磁中矿的稀土浮选尾矿回收铌得到富铌铁精矿的若干浮选工艺条件及浮选药剂。
Low and medium-grade niobium oxide ore of the Zhudong mining area, Baiyan Obe mine, is of great value to us in our comprehensive covery of Baiyan Obo mine's mineral resources. The authors discuss the characteristics and separation properties of main niobium minerals, concluding that low intensity magnetic separation-high intensity magnetic separation is an effective way to prcliminarily concentrate niobium. The niobium-enriched magnetic middling obtained by high intensity magnetic separation is separated by f]otatation, obtaining a niobium and rare-earth-enriched iron concentrate or higher grade niobium-enriched iron concentrate. The authors describe some operational conditions and reagents for recovering niobium from the niobiumenriched magnetic middling by flotation.
