摘　　要：针对非洲某铜钴精矿进行了化学物相研究,在其基础上进行了焙烧-浸出试验研究。研究结果表明:该矿的最佳焙烧温度为620℃,焙烧时间5.0 h、焙砂进行两段浸出,铜钴两段总浸出率可分别达到98.03%、91.93%。Chemical phase-analysis was studied with Cu--Co concentrate of Africa, and roast-leaching experiments were researched. The results show that the optimum roasting conditions were ：roasting temperature of 620 ℃, roasting time of 5.0h.The leaching rate of copper and cobalt is 98.03% and 91.93% respectively after roasting through the two-stage acidic leaching process.
