摘　　要：为促进河南上房沟高滑石型难选钼铁矿石选矿技术水平的提高,对其进行了工艺矿物学研究。研究结果表明:矿石中主要有用矿物为辉钼矿和磁铁矿;有害矿物滑石含量高、辉钼矿和磁铁矿粒度细是矿石难选的主要原因;矿石中磁铁矿与滑石关系紧密而与辉钼矿几乎没有毗邻关系,因此在选矿过程中可以考虑先通过粗粒磁选将滑石随同磁铁矿分离出来,然后再对非磁性产物进行辉钼矿浮选。To promote beneficiation level of high-talc-based refractory kamiokate ore of Shangfanggou in Henan,the paper studied its process mineralogy.The results showed that the main valuable minerals are molybdenite and magnetite;High level of harmful talcum and fine grain of molybdenite and magnetite are the main reasons of being difficult to separate.There are closely relationship between magnetite and talcum,while nearly none of magnetite border on molybdenite.Therefore,in beneficiation process,talc accompanying with magnetite are firstly considered to be separated by rough magnetic separation,and then non-magnetic minerals are separated from molybdenite by flotation.
