摘　　要：采用常压氧化酸浸法从钴白合金中浸出钴和铜,研究考察了浸出时间、浸出温度、液固比和硫酸浓度对钴白合金中钴和铜浸出率的影响。得出酸浸的最优条件为:浸出时间6 h,浸出温度70℃,液固比9∶1,硫酸的浓度2.0 mol/L,此时钴的浸出率为88.7%,铜的浸出率为86.4%。The Co and Cu are prepared by ordinary pressure leaching from Co white alloy.The effects of experimental conditions,such as leaching time,leaching temperature,liquid-to-solid ratio and concentration of the sulphuric acid are investigated.The optimal conditions for acid leaching are that leaching time of 6 h,leaching temperature of 70℃,liquid-to-solid ratio of 9∶1,concentration of the sulphuric acid of 2.0 mol/L.The leaching rate of Co and Cu is 88.7%,86.4%under the following conditions.
