摘　　要：根据几内亚某地区的铁矿地质勘探资料,对该地区某高磷铁矿石中磷元素在各类矿物中的赋存情况进行研究。为满足国际市场对进口铁矿石的磷元素的要求(P≤0.07%),结合磷在铁矿石中以胶体状态存在的现象,探究一种以露天采矿机采矿-湿筛脱泥的降磷方法。According to the geological exploration data of iron ore in a region of Guinea,the occurrence of phosphorus element in a high phosphorus iron ore in various minerals was studied.In order to meet the requirements of the international market on the phosphorus element of imported iron ore(P≤0.07%),and combined with the phenomenon that phosphorus exists in colloidal state in iron ore,a method of phosphorus reduction using open-pit mining machine-wet screening desliming was explored.
