摘要
以江铜集团贵溪冶炼厂的高含量杂质铜阳极泥作为原料,采用加压酸浸的方法对该铜阳极泥进行预处理,对铜、砷、碲、锑、铋、锡等杂质元素和贵金属银的浸出进行了研究。结果表明,该方法可以将铜、砷、铋较完全脱除,碲、锑大部分脱除,锡部分脱除,而贵金属银基本没有损失。
The high impurity contained copper anode slime in Guixi Smelter is pre-treated by pressurized acid leaching method and the leaching behavior of copper, arsenic, tellurium, antimony, bismuth, tin and silver in copper anode slime is studied. The results show that this method can obtain thoroughly removal of copper, arsenic, bismuth and mostly removal of tellurium, antimony and partly removal of tin while not any loss of precious metal silver.
