Abstract

본 발명은 전해 채취시 생성되는 동(CU)과 비소(As)를 함유한 전착물을 분리하여 동을 함유한 용액은 재사용하고, 비소용액은 아미산 형태로 회수하는 처리방법에 관한 것으로, 동(CU)과 비소(As)를 함유한 비소전물을 산으로 참출하여 침출액을 얻는 공정과, 이 침출액을 혼합용매로 추출하여 동을 합한 유기상과 비소를 함유한 추출잔액으로 분리하는 용매추출 공정서, 상기한 동을 함유한 유기상은 황산 동액으로 탈거하여 고순도 황산동 용액을 얻는 공정과, 상기한 비소를 함유한 추출잔액은 아황산가스로 환원한 다음 산성화 처리하고 증발 농축하여 아미산을 정출시키는 공정으로 이루어진 동과 비소를 함유한 전물(澱物)의 처리 방법에 관한 기술임.The present invention relates to a treatment method of separating electrodeposits containing copper (CU) and arsenic (As) generated during electrolytic extraction, reusing copper-containing solutions, and recovering arsenic solutions in the form of amic acid. Extracting the arsenic material containing CU) and arsenic (As) with an acid to obtain a leachate, and extracting the leachate with a mixed solvent and separating the leachate into an organic phase and an arsenic-containing extracting residue, The organic phase containing copper is removed with a copper sulfate solution to obtain a high-purity copper sulfate solution, and the extract residue containing arsenic is reduced with sulfurous acid gas, acidified, evaporated and concentrated to crystallize amic acid. A technique for the treatment of whole things containing and arsenic.
