本文主要介绍了硫酸盐形态硫的选矿脱除方法，通过反浮选可以把铁精矿的硫含量降到0.13%，硫的脱除率为93.43%。
In this paper, Mostly introduce to desulfurize method of sulphate form, pass in reverse floatation May hold sulfur of iron concentrate drop to 0.13%, sulfur get ride of ratio became 93.43%.
该铁精矿通过反浮选降硫使含硫降至0.26%，最终获得优质的钒钛磁铁矿精矿。
Then S content in concentrate can be lowered to 0.26% by reverse flotation desulphurization flow-sheet, with high-grade magnetite concentrate finally achieved.
根据试验结果，推荐的试验流程为阶段磨矿—弱磁选—硫铜混浮—铁精矿脱硫选矿工艺流程。
According to the test results, recommend the experiment process as stage grinding-low intensity magnetic separation-sulfur-copper bulk flotation-desulfurization of iron concentrate.
试验表明：采用磁选柱选别可得到6 5 %以上的铁精矿。但精矿中硫含量偏高，需要进行降硫处理。
The tests showed that an iron concentrate having a 65% iron grade could be obtained, but it had a rather high content of sulfur that should be reduced by some additional treatment.
