|Title:||METAL RECOVERY METHOD INCLUDING CYANIDE REMOVAL AND METAL RECOVERY SYSTEM THEREFOR|
The present invention relates to a metal recovery method including cyanide removal and a metal recovery system therefor. A metal recovery method including cyanide removal according to the present invention comprises the steps of: preparing leachate containing a metal ion and cyanide; preparing an electrolyzer which receives the leachate and reduces and precipitates the metal ion of the leachate on a surface of a negative electrode when the leachate is supplied to a reaction space formed between a positive electrode and the negative electrode surrounding the positive electrode; and supplying the leachate and a decomposition solution capable of decomposing the cyanide to the electrolyzer.
