| 摘 要： | 某氰化提金尾渣中铁矿物种类多、磁性差异大,矿物粒度细,采用弱磁、强磁依次选别工艺流程获得的选矿指标不佳。采用弱磁、强磁交叉选别工艺流程进行铁的回收试验研究,并对试验条件进行了优化。在最佳条件下,获得了TFe品位为62. 43%,回收率为21. 62%,产率为12. 54%的磁铁精矿,以及TFe品位为50. 51%,回收率为21. 36%,产率为15. 31%的褐铁精矿。该工艺流程使得磁铁精矿与褐铁精矿分配合理,进一步提高了综合经济效益。

| Abstract: | The iron minerals in the tailings of a gold cyanidation process are various in kinds and magnetism and in fine grains so that weak magnetic and strong magnetic separation in turn doesn’t achieve satisfactory index. The paper chose alternating weak magnetic and strong magnetic separation to carry out iron practical experiment and optimized the experimental conditions. Under the optimal conditions,the TFe grade of the magnetite concentrate obtained is 62. 43 %,the recovery rate is 21. 62 %,productivity is 12. 54 %,the TFe grade of the limonite concentrate obtained is 50. 51 %,the recovery rate is 21. 36 %,productivity is 15. 31 %. The process has reasonable distribution of magnetite and limonite,further improving comprehensive economic profits. |
