泡沫浮选萃取处理锌镉渣的工艺研究

Study on the Technique of Zinc - Cadmium Waste Residue Treatment by Flotaextraction

研究了泡沫浮选萃取全湿法处理锌镉废渣工艺。试验结果表明：泡沫浮选萃取法分离溶液中的Ｃｄ２＋Ｚｎ２＋离子，具有选择性强、分离系数高、处理量大和无环境污染等优点；采用该工艺处理锌镉废渣，可制得优质硫酸锌和ＺＢ－硼酸锌。

The flotaextraction technique of zinc - cadmium waste residue treatment has been investigated. The results show that the flotaextraction technique is characterized by its strong selectivity high separation coefficient and large production on the separation of Zn2 + /Cd2 + in aqueous solution.
