이에 따라 본 발명은 침출액에 함유되어 있는 구리, 아연, 카드뮴 및 니켈과 같은 유용금속을 간편하고 효율적으로 추출 및 분리할 수 있다.
The present invention relates to a method to extract and separate the copper, zinc, cadmium and nickel from the leachate, the leachate collection collecting the leachate contains a useful metal (S100); It was added to the leachate collection step (S100) for collecting the leachate hydroxy oxime extractants of copper through a selective extraction step that extracts as a copper (S200); Copper extraction step (S200) and the remaining copper is extracted first filtrate cationic extractant selective extraction of zinc and cadmium in the step of extracting the zinc and cadmium was added to a (S300) through; And that over the zinc and cadmium extraction step (S300) of the zinc and cadmium are extracted including a nickel recovery step to recover the nickel (S400) from the rest of the second filtrate with the technical features.
Accordingly, the present invention can be easily and efficiently extracted and separated by the useful metals, such as copper, zinc, cadmium, and nickel contained in the leachate.
