【摘要】 根据安徽某铜矿尾矿的矿石性质,采用磁选—铁粗精矿分级—粗粒精矿再磨—磁选—浮选流程,试验结果表明,可获得产率54.75%,铁品位67.59%,回收率84.74%,含硫0.047%的铁精矿。提高了该尾矿的铁精矿品位和回收率,并降低了铁精矿中的硫含量。更多还原

【Abstract】 According to the ore characters of an Anhui copper tailing,the technical process of magnetic separation-classification of rough iron concentrate-regrinding of coarse concentrate-magnetic separation-flotation was adopted.Then these results showed that iron concentrate with yield of 54.75%,iron grade of 67.59% and sulfur content of 0.047% at an 84.74% iron recovery was obtained.Thus the grade and recovery of iron concentrate from the tailings can be improved and sulfur content can be reduced.更多还原
