粗铜冶炼电收尘烟灰的湿法处理

Hydrometallurgy of Electric Precipitator Dusts from Blister Copper Smelting

粗钢冶炼电收尘烟灰按原设计经过配料、混捏，返回炼钢炉熔炼，不仅不经济，也给炼钢生产带来危害。本文寻求水浸处理该烟灰的湿法封闭流程，既可合理回收烟灰中有价金属，做到无废水排放，又能在低投资下获得明显经济效益。

Electric precipitator dusts from blister copper smelting were de-signed to revert copper smelter. It isn' t only economical, but also bring to the detri-ment of copper press. This paper intreduces a technology to leach these dusts with water. It may recover valuable metals of dusts reasonably, haven' t waste water to discharge, and marked economic effect has been got in case smaller investment.
