提高精矿质量和矿产资源利用率

Improve the Quality of lron Concentrate and the Utilization Ratio of Mineral Resources

对低硫低铜磁铁矿进行了不同工艺研究， 采用先浮后磁和使用高选择性捕收剂可获得精矿含铁６３ ．１８ ％ ， 回收率８４ ．３４ ％ ， 含硫０ ．３８ ％ 的合格铁精矿； 含铜１３ ．８３ ％ ，回收率５１ ．４１ ％ 的铜精矿；含硫３５ ．１９ ％ ，回收率７３ ．５９ ％ 的硫精矿， 明显提高了矿产资源利用率。

In this paper the different technology separating low sulphur-low copper magnetite is researched.lt can obtain a lron concentrate of TFe 13.185 and S 0.38%with a recovery of 84.34%, a Copper concentrate of Cu 13.83%,with a recovery 51.41%and a Sulphur concentrate of S 35.19%,with a recovery 73.59%.The Utilization ratio of mineral resources is improved.
