摘要
研究了从某厂炼铜生产过程中产出的高砷含铋物料中回收铋。这种物料中 ,w( Cu) =1 6% ,w( As) =39%。选择酸浸—沉铋—脱砷—重溶—置换工艺 ,铋浸出率 >96% ,回收率 >90 %。
Recovery of bismuth from bismuth materials contening arsenic yielded in a copper smelter is studied.In the materials , w (Cu) is 16%, w (As) is 5.39%.The materials were cured using the process of acid leaching —precipitation—dearsenication—redissolution,leaching rate and recovery of Bi are over 96% and 90%.
