The metal cyanide complex content in the heap leaching circulation solution in a gold mine is high.On the basis of analyzing the mechanism of different processes to remove copper cyanide complex and (ferrous)ferric cyanide complex,experimental study on removal with single process and joint process is conducted.The results show that the ferrous salt precipitation method,ferric salt precipitation method and zinc salt precipitation method all have good removal effect on (ferrous)ferric cyanide complex;acidification method and vulcanization method both have good removal effect on copper cyanide complex.In terms of economics and secondary pollution,it is recommended that the joint process of ferrous salt precipitation-acidification be used to remove metal cyanide complex from heap leaching circulation solution.
