摘　　要：中国的铁矿资源日益趋于贫、细、杂。高磷硫含量的铁矿资源的高效开发和利用日益受到了广大科学研究者的重视。高磷铁矿石的脱磷方法众多,如浮选法、化学浸出法、微生物法、磁化焙烧法,但浮选法因选矿成本低,分选指标相对稳定而广泛用于高磷硫铁矿的分选。鉴于近几年国内有关高磷硫铁矿石开发和利用的综述报道较少,本文首先针对含磷铁矿分选工艺进行总结,又对浮选法脱磷硫着重介绍,并提出了一种磷硫同步浮选脱除的新方法。Iron ore resources in China are increasingly becoming lean,thin and miscellaneous.The efficient development and utilization of iron ore resources with high content of phosphorus and sulfur has increasingly attracted the attention of researchers.There are many dephosphorization methods for high-phosphorus iron ore,such as flotation method,chemical leaching method,microbial method and magnetization roasting method.However,the flotation method is widely used due to the low cost and relatively stable separation index.In view of the few reviews on the development and utilization of high phosphorus and sulfur iron ore in China in recent years,this paper first summarizes the phosphorus-containing iron ore sorting process,and introduces the flotation dephosphorization process,also a new method for synchronization flotation separation of sulphur and phosphorus in iron ore by induced activation of calcium elements was provided.
