Abstract: 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.

Key words: Copper-containing acid mine drainage, Precipitation-flotation, Resource recovery
