摘要: 攀西钒钛磁铁矿硫钴粗精矿中硫、钴品位低,达不到综合利用要求。通过工艺矿物学和选矿试验研究得出:钒钛磁铁矿中主要硫化矿物为黄铁矿和磁黄铁矿,钴在黄铁矿和钴镍黄铁矿中富集。以硫酸为调整剂,丁黄药为捕收剂,硫酸铜为活化剂,石灰为分离抑制剂,经过“精选—分离”流程可以同时得到Co品位0.74%,S品位41.07%的钴硫精矿和S品位35.58%的硫精矿,钴、硫的综合回收率分别达到84.45%和91.14%,实现钒钛磁铁矿中钴、硫资源的综合利用。

Abstract: In west panzhihua vanadium-titanium magnetite, the grade of sulfur and cobalt were low in the S-Co rough concentrate, which cannot meet the demand of comprehensive utilization. Thorough research was conducted on the process mineralogy and beneficiation experiment to improve the utilization of sulfur and cobalt in west panzhihua region. The main sulfide mineral in vanadium-titanium magnetite are pyrite and pyrrhotite, cobalt is enriched in pyrite and hengleinite. By using sulfuric acid, butyl xanthate, copper sulfateand lime in combination, through the "cleaning-separation" process, the Co-S concentrate containing 0.74% Co, 41.07% S and sulfur concentrate containing 35.58% S can both be obtained, the comprehensive recovery of Co and S reaches 84.45% and 91.45%.

Key words: S-Co rough concentrate, Hengleinite, Comprehensive utilization
