选铁尾矿回收稀土生产实践

Production Practice of Recycling Rare Earth from Tailings after Beneficiating Iron

沃尔特矿业处理多种矿石,选铁尾矿中稀土含量较高,针对混合矿矿石性质复杂,影响因素多的问题,采用浮选方法,通过单独处理的思路,将沃尔特尾矿中的稀土进行有效回收。结果表明:在较佳的实验条件下,最终得到精矿品位为52.00%、回收率为56.05%的稀土精矿,获得了较为显著的经济效益。

Woerte Mining Co.,Ltd.processes various ores.The content of rare earth in the tailings after beneficiating iron is higher,the rare earth in tailings of Woerte is effectively recycled with the flotation method and thought of individual processing aiming at the problems of complex ore properties and many influencing factors for mixed ore.The results showed that under the better experimental conditions,the rare earth ore concentrate with concentrate grade of 52.00%and recovery rate of 56.05%was finally obtained so that more significant economic benefits were obtained.
