中文摘要:
      【】该研究针对以磁黄铁矿为主的硫铁尾矿进行了选矿与焙烧试验,通过浮—磁—再磨—浮选联合流程可以获得两个不同级别的硫精矿,硫总回收率为93.26%;铁精矿含铁63.88%,含硫1.66%,铁回收率为23.29%。通过焙烧可以获得硫含量达标的铁精矿,但增加了生产成本。因此硫含量超标的铁精矿是作为产品出售,还是进一步焙烧脱硫,需进行综合比较。
英文摘要:
      the study aimed at the selection and roasting test of iron ore tailings, mainly ferropyrite, which can obtain two different grades of sulfur concentrate through floating - magnetic - regrinding - flotation process, and the total recovery rate of sulfur is 93.26%. Iron concentrate contains 63.88% iron and 1.66% , iron recovery rate of 23.29%. Through roasting test, the iron concentrate with the content of sulfur content is achieved, but the production cost is increased. Therefore, the iron concentrate of high sulfur content is to be sold as a product, or further roasting and desulfurization. We need to make a comprehensive comparison.
