  从原矿多项分析结果知道,铀含量为0.016%,Nb2O5含量为0.028%,铅含量为0.75%,它们品位都很低,铁、硫品位也不高。根据矿床贪、杂、难这一特点和矿石性质、矿物组成特征,拟定采用原矿经水力分级、选矿作业以跳汰选矿为主,辅以摇床、螺旋溜槽、离心机组成的重选抛尾工艺,为开发利用低品位铀铌铅矿创造了条件。

  对该低品位的铀铌铅多金属矿采用以跳汰选矿为主的重选抛尾工艺能够抛弃80%以上的尾矿,有价金属得到初步富集。重选抛为得到的粗精矿经磁—浮 分离可获铅、铁、硫精矿、铀铌精矿。铀铌精矿进一步通过冶金分离提取重铀酸铵和五氧二铌产品,使原来贫、杂、难得低品位铀铌铅矿床的工业利用成为可能。
