| 摘 要： | 鲕状赤铁矿矿石中赤铁矿嵌布粒度极细,矿物组成复杂,磨矿中又易泥化,使其成为国际攻关难题.对张家口地区鲕状赤铁矿进行了强磁-重选的试验研究.如采用"阶段磨矿-强磁选抛尾-重选"的工艺流程.结果表明,在原矿铁品位47.66%,磨矿细度-0.074mm95%,经强磁和重选后,可获得铁品位61.01%,回收率为47.85%的铁精矿. |

| Abstract: | With the feature of finely-disseminated particle, complex mineral composition and easily sliming in the grinding process, oolitic hematite is considered to be a difficult problem of mineral processing in the world. The tests of high intensity magnetic separation-gravity concentration for oolitic hematite ore in Zhangjiakou District were conducted. The flowsheet of stage grinding--high intensity magnetic separation to discard tailing-gravity separation was used in the tests. The test results showed that the ... |
