摘要
新疆某铅锌银铁多金属矿石,含有磁黄铁矿2%,在铅锌银浮选尾矿综合回收磁铁矿的流程中,致使铁精矿硫含量超标。通过对铅锌浮选尾矿选铁除硫试验研究,确定除硫药剂制度为:组合活化剂硫酸+Lc(368+20)g/t,捕收剂丁黄药+DH(15+5)g/t,可以获得全铁品位67.97%,含硫0.19%的铁精矿,磁铁矿中铁回收率达87.64%的优良指标,且除硫药剂成本低廉。
A lead-zinc-silver-iron polymetallic ore in Xinjiang contains 2% of pyrrohotite. The sulfur content of iron concentrate exceeds the standard when the comprehensive recovery of magnetite was carried on from the lead-zinc- silver flotation railings. The reagent system of sulfur removal was determined through the research on iron separation and sulphur removal from the lead-zinc flotation tailings. When the dosage of the combined sulfuric activator was 368g/t＋Lc 20g/t and the collector of butyl xanthogen 15g/t＋DH 5g/t, an iron concentrate with 67.97% of TFe and 0.19% of S was obtained. The iron recovery in magnetite reaches 87.64%. The index is satisfactory.
