摘　　要：我国的钽资源丰富 ,占世界钽资源的第五位 ,但我国钽铌矿资源品位低 ,粒度细 ,矿石性质复杂 ,多属难选矿石。作者详细研究了蚀变花岗岩型钽铌矿—我国南方某钽铌矿的工艺矿物学特性 ,并对其可选性进行了分析。该研究结果对选矿工艺流程的制定有着重要的指导作用。There are abundant tantalite resources in our country, which is situated fifth in the world. But it is a difficult to concentration because of its low grade with fine dissemination sizes and complicated ore character. The processing mineralogy character for altered granite pattern tantalite-columbite ore and its processibility has been studied. This studied result is important to design processing flowsheet.
