| description | 본 발명은 1차 및 2차 원료로부터 아연을 회수하는 개선된 방법에 관한 것으로, 상기 공정은 원료에 함유된 아연 중량과 침출 용액의 부피 사이의 비가 산성 수용액 m3당 적어도 20kg 아연인 제1 침출 단계; 중화 단계; 및 유기 추출제의 존재하에 용매 추출 단계를 포함하며, 여기서 온도는 47 내지 52℃로 유지된다.
The present invention refers to an improved process for recovering zinc from primary and secondary raw materials, said process comprising a first leaching step wherein the ratio between the zinc weight contained in the raw material and the volume of the leaching solution is at least 20 kg zinc per m3 of acid aqueous solution; a neutralization step; and a solvent extraction stage in the presence of organic extractant, wherein the temperature is maintained from 47 to 52°C. |
