铜堆浸厂含铜酸性废水沉淀浮选处理试验研究

Test on Precipitation-Flotation Treatment of Copper-Containing Acid Mine Drainage from Copper Heap Leaching Plant

采用沉淀浮选法处理紫金山金矿铜堆浸厂含铜酸性废水,分别使用硫化钠和丁铵黑药沉淀浮选铜,使用石灰和油酸沉淀浮选铜和铁,不仅使处理后的水可达标排放,还可有效回收废水中的铜和铁,降低处理成本。

The application of precipitation-flotation method in treating copper-containing acid mine drainage from copper heap leaching plant in Zijinshan Gold Mine, which uses sodium sulfide and dibutyl ammonium aerofloat to precipitate and float copper, and slime and oleic acid to precipitate and float copper and iron, can not only enable the treated water to reach the discharge standard but also effectively recover the copper and iron from the waste water so as to reduce the treatment cost.
