摘　　要：本选矿试验探讨了TFe品位11.66%、Ti O_2品位5.24%的含铁辉长岩中钛铁矿的选矿方法。通过试验,针对其铁钛矿物含量低且嵌布相对较细的特点,采用优先选钛的主体工艺,"弱磁+两段强磁+一粗五精浮选"的流程,获得产率2.97%、Ti O_2品位47.00%、回收率28.66%的高钛、含钒的优质钛精矿。实现资源综合利用,为含铁辉长岩中钛铁矿回收利用提供了技术依据。The study discusses the beneficiation method which recovery of titanium iron ore from ferrogabbro of TFe grade 11.66%, TiO2 grade 5.24%. Through experiment, aiming at the characteristics of low content of the ferrotita- nium mineral and relatively fine disseminated, the process＇ Weak magnetic＋Two stage strong magnetic＋flotation with one section of rough selection and Five section of selection＇ is quality titanium concentrate containing vanadium with yield 2. prehensive utilization of resources provides technical basis to adopted, which can get high content titanium and high 97% ,Ti02 47.00% and recovery of titanium iron recovery rate 28. 66%. Comore from ferrogabbro.
