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。
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 re- search 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%.
