도금폐액 및/또는 박리액으로부터 금을 회수하는 방법How to recover gold from plating waste and / or stripping liquid

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

Claims (1)

금도금 폐액 및/또는 박리액에 수산화나트륨 용액과 치아 염소산 나트륨용액을 가하여 Sodium Aurate를 형성시키고, 아연 미분말을 가하여 미세입자상의 금을 생성시킨 다음, 불순물을 제거하기 위하여 진한 염산으로 1차 처리를 하고 다시 진한 질산으로 2차 처리를 하여 불순물을 제거한후, 잔류금 미세분말에 왕수를 가하여 용해 시켜 염화금산을 용액을 제조하고 염화금산 용액을 하이드라진으로 처리하는 것을 특징으로 하는 금도금 폐액 및/또는 박리액으로부터 금을 회수하는 방법.Sodium Aurate was formed by adding sodium hydroxide solution and sodium chlorate solution to the gold plating waste solution and / or stripping solution, and fine zinc powder was added to form gold in fine particles, followed by primary treatment with concentrated hydrochloric acid to remove impurities. After further treatment with concentrated nitric acid to remove impurities, gold plating waste liquid and / or stripping solution, characterized in that the solution is dissolved by adding aqua regia to the residual gold fine powder to prepare a solution of geum chloride and chlorazine solution with hydrazine Recovery of gold from the process. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
