摘要
综述了铜冶炼开路烟尘的主要化学组成及其赋存状态,讨论了现阶段综合回收铜冶炼开路烟尘的三种处理工艺,即火法工艺、湿法工艺以及联合工艺。系统地比较了三种工艺各自的优缺点,总体上看,现阶段铜冶炼开路烟尘的湿法处理工艺具有工作环境好、适用范围广、能耗较低和技术手段丰富等优点,在试现铜冶炼开路烟尘中有价元素的综合利用上具有较好的工业化应用前景。
The main chemical compositions and occurrence state of open-circuit dust in copper smelter were reviewed in this paper. Three processing techniques including pyrometallurgical process, hydrometallurgical process and pyro–hydrometallurgical process to recover the dust comprehensively were discussed, and the advantages and disadvantages of them were systematically compared. On the whole, the hydrometallurgical processing is eff ective and fl exible for treating such materials because of its good working environment, wide application range, low energy consumption, rich technical means, etc, and thus has a good prospect of industrial application on comprehensive recovery of open-circuit dusts in coppersmelter.
