摘　　要：攀西地区钒钛磁铁矿中的钛铁矿主要采用粗、细粒分级分选工艺,存在流程复杂及能耗较高的问题。首先对攀西某选厂粗、细粒钛铁矿性质进行了分析,其次开展了粗粒钛铁矿、细粒钛铁矿单一浮选试验及混合浮选试验研究。结果表明,粗、细粒钛铁矿混合浮选指标较好,工艺可行。对简化钛浮选流程、降低生产成本和提升钛铁矿选矿水平提供了一定借鉴。Ilmenite in the west of Panzhihua area is mainly used in coarse-grained and fine-grained classification and separation process,but there are some problems such as complicated process and high energy consumption.In this paper,the properties of coarse-grained and fine-grained ilmenite were firstly analyzed,and then the flotation indexes of coarse-grained and fine-grained ilmenite were separately analyzed.On this basis,the mixed flotation experiment of coarse-grained and fine-grained ilmenite was carried out.The results show that the mixed flotation process of coarse-grained ilmenite is feasible.The research results of this paper provide some reference for simplifying titanium flotation process,reducing production cost and improving ilmenite beneficiation level.
