摘　　要：本文以工艺矿物学为基础,研究从攀西某钒钛磁铁矿选铁尾矿中回收硫钴资源的关键因素和工艺流程。研究结果表明,含钴黄铁矿、黄铁矿和磁黄铁矿的分离是实现选铁尾矿中硫钴资源综合回收的关键,强磁选是实现含钴黄铁矿分离的有效措施,采用浮选—精矿再磨再选—高场强阶段磁选工艺可以得到含钴0.40%、含硫50.45%的钴硫精矿,钴和硫回收率分别为6.74%和19.07%,同时得到含硫37.23%、硫回收率20.81%的硫精矿,实现选铁尾矿中硫、钴资源的综合回收。Based on process mineralogy, the key factors and processes of benefit cobalt and sulfur from iron ore tailing of vanadium-titanium magnetite was studied. The results indicate that the separation of Co-bearing pyrite,pyrite and pyrrhotite is the key to achieving comprehensive recovery of cobalt and sulfur resources, high intensity magnetic separation is an effective measure to benefit Co-bearing pyrite. By the flotation concentrate regrinding-flotation refining high magnetic stage separation process, the cobalt sulfur concentrate which containing 0.40% Co and 50.45% S can be obtained, the recovery of Co and S are6.74% and 19.07%, in the mean time, a sulfur concentrate containing 37.23% S can also be obtained,the recovery of S is 20.81%, which realized the comprehensive utilization of cobalt and sulfur from iron ore tailings in vanadium-titanium magnetite.
