-
摘要: 通过对选铁尾矿中回收铁精矿的工艺考查、分析,进行了粗精矿再磨工艺的试验。结果表明,粗精矿经再磨后能选出含铁品位达51.5%的合格铁精矿,且可提高精矿产量。Abstract: The experimental study on the re-grinding of primary concentrate has been conducted through the investigation and analysis on the process to recover iron concentrate from tailings of ore dressing. The results indicate that iron concentrate of 51.50% grade could be obtained after regrinding of primary concentrate and the production of iron concentrate could be raised.
