摘　　要：青海某地含少量氧化矿的磁铁矿,矿物组成简单、有用矿物嵌布极细,属于难选矿石。采用阶段性磨矿、阶段性弱磁选及反浮选工艺后,磨矿细度-500目达到95%以上,铁精矿TFe 61.11%,回收率为45.98%,产率为24.74%。The magnetite ore from Qinghai province with fewer minerals while contenting a little iron oxidized mineral is very difficult to be separated because of ultra - fine - grained dissemination of the iron minerals. By a process of ＂stage grinding - stage low - intensity magnetic separation - reverse flotation＂ , a concentrate of 61.11% Fe can be obtained with a recovery of 45.98% and a yield of 24.74%. After grinding, - 500 mesh in the minerals should be over 95%.
