河南省泌阳县台山大红口组地层富含铌钽，通过光薄片鉴定、人工重砂、电子探针及选矿试验，确定了该区大红口组铌钽矿物的组成及含量，并研究了含铌钽矿物的化学成分、粒度与嵌布特征和铌钽元素的赋存状态。其铌钽矿物主要为铌钛铁矿、铌铁金红石、铌铁矿三个矿物种，以富铁和富钛类为主。粒径一般为-0.043+0.01 mm 粒级之间。铌钽矿物主要有两种嵌布形式，包裹体分布型占66.90%，粒间分布型占30.72%。选矿试验证明：该区大红口组中的铌钽在目前经济技术条件下暂无法利用，但其中的钾长石在玻璃和钾肥工业中具有较好的应用前景。

Through analyzing tantalum and niobium-rich in Taishan Biyang county, Henan province, using optical microscopy, manual artificial heavy concentrate, electron probe micro-analyzer(EPMA) and mineral processing test, this paper identifies composition and content of niobium tantalum ore of Dahongkou group stratum in this area. Detailed study is carried out in chemical composition, grain size, embedded characteristics and the state of niobium tantalum element. There are mainly three types of niobium tantalum minerals which are niobium ilmenite, niobium rutile, and columbite, with rich iron and titanium-rich based. Average particle size range is 0.043+ 0.01 mm. There are mainly two types disseminated form of Niobium tantalum minerals, which are inclusion type accounting for 66.90% and intergranular type accounting for 30.72%. On the basis of the detailed study, the mineral processing test proves niobium tantalum of Dahongkou group has a good application prospect in the potash and ceramic industry in current economic and technological conditions.
