中文摘要: 采用浮选、硫酸化焙烧、酸浸、萃取电积、除铁沉钴流程从刚果(金)铜钴精矿中回收铜钴。结果表明,最佳焙烧条件为:粒度-0.074 mm占90.77%,添加7.5%的Na2SO4在700 ℃焙烧30 min。焙砂进行两段浸出,铜钴的浸出率分别达到97.61%和95.92%。
Abstract:Copper and cobalt were recovered from copper and cobalt concentrates from CMSK Ltd of DR Congo with a series of processes including floatation, sulfating roasting, acidic leaching, extraction and electro-deposition (SX-EW-Co), iron removing and cobalt precipitation. The results show that the optimum roasting conditions including particle size of -0.074 mm of 90%, Na2SO4 dosage of 7.5%, temperature of 700 ℃, and roasting time of 30 min. The leaching rate of copper and cobalt is 97.61% and 95.92% respectively after the calcine is leached through the two-stage acidic leaching process.
