摘　　要：某铁尾矿钴含量约为0.012%,钴资源未得到有效回收。为考察该钴资源回收的可行性,本文进行了相关试验,重点研究了浮选浓度和矿泥对钴矿物浮选回收的影响,研究发现脱泥及适当的浮选浓度有利于钴矿物的浮选回收。最终确定采用旋流器脱泥,在浮选浓度为25%的条件下,以丁基黄药为捕收剂,采用一粗两精一扫的工艺流程,可获得品位为4.65911%,钴回收率为54.41%的钴精矿。An iron mine tailing with the cobalt content of 0.012%has not been effectively utilized.To investigate the feasibility of cobalt resource recovery,related experimental study was carried out in this paper,focusing on the effects of flotation concentration and slime on cobalt mineral flotation recovery.The study found that desliming and appropriate flotation concentration are beneficial for cobalt mineral flotation recovery.Finally,it was determined to use a cyclone for desliming.Under the condition of a flotation concentration of 25%,butyl xanthate was used as the collector,and a process flow of one coarse,two fine,and one sweep was used to obtain a cobalt concentrate with a grade of 4659.11 ppm and a cobalt recovery rate of 54.41%.
