摘　　要：云南富宁县良子老寨钛铁矿原矿含TiO_(2)3.88ω%,TFe 15.50ω%;TiO_(2)是选矿回收的目的元素,60.38%赋存于钛铁矿中,为可选钛。矿石中主要目的矿物为钛铁矿,主要脉石矿物为褐铁矿、高岭石、绿泥石、石英等。钛铁矿粒度主要在细粒-中粒级,采用“弱磁除铁-高梯度强磁抛尾-钛粗精矿摇床精选”作为联合选矿工艺流程,可实现钛铁矿与脉石矿物之间的有效分离。In Liangzilaozhai ilmenite deposit,the raw ore contains TiO_(2)3.88%;TFe 15.50%,The TiO_(2) is the object material of dressing recovery,60.38%of it is in ilmenite,which is the washable Ti.In the ore,the main object mineral is ilminite,main gangue are limnit,kaolinite,chlorite,quartz,etc.The ilminite grain size is mainly fine-medium.Taking“weak magnet remove Fe-high gradient intense magnet get rid of tail-Ti coarse concentrate dressed precisely by shaking”as combination dress technologic circuit,which can carry out the effective separation of ilmenite from gangue.
