| 摘 要： | 含砷金铜精矿火法熔炼电尘灰是铜冶炼熔炼车间产出的中间产物,成分复杂,较难处理,属于典型危废。以山东某冶炼公司含砷金铜矿熔炼产出的中间产物电尘灰为原料,采用双氧水为氧化剂进行酸性氧化浸出,最佳浸出工艺条件为:双氧水用量120kg/t、酸性氧化浸出时间2h、浸出温度80℃、酸度60g/L,铜和砷的浸出率分别达到92.30%、87.50%以上。为铜冶炼企业湿法处理电尘灰提供了一条新途径。

| Abstract: | Dust of electrostatic precipitator of arsenic-bearing auricupride smelting is an intermediate product produced by copper smelting workshop.It is a typical hazardous waste due to its complex composition and difficult to treat.Dust of electrostatic precipitator from a smelting company in Shandong province was oxidation acidity leached with hydrogen peroxide as oxidant.The results show that leaching rate of copper and arsenic is 92.30%and 87.50%above respectively under the optimum conditions including dosage of hydrogen peroxide of 120 kg/t,leaching time of 2 h,leaching temperature of 80℃,and acidity of 60 g/L.It provides a new approach for copper smelting companies to deal with dust of electrostatic precipitator by hydrometallurgical process. |
