Zusammenfassung:	According to one embodiment of the present invention, provided is a method for recovering a valuable metal through a submerged arc furnace comprising a: a step of preparing a mixture of an electronic scrap and a waste catalyst, b: a step of injecting the mixture and flux of step a into a submerged arc furnace and performing a melt-reduction treatment, and c: a step of separating a crude metal and a slag manufactured in step b. According to another one embodiment of the present invention, provided is the method for recovering a valuable metal through a submerged arc furnace comprising i: a step of preparing a mixture of the electronic scrap and a low-grade copper sludge, ii: a step of injecting the mixture and flux of step i into the submerged arc furnace and performing the melt-reduction treatment, and iii: a step of separating the crude metal and the slag manufactured in step ii. Therefore, the present invention has an effect of overcoming the limitations of treating each raw material separately. 본 발명의 일 실시예는 a: 전자스크랩 및 폐촉매를 혼합한 혼합물을 마련하는 단계; b: 상기 a 단계의 혼합물과 플럭스를 서브머지드 아크로에 투입하고, 용융환원 처리하는 단계; 및 c: 상기 b 단계로 생성된 조금속 및 슬래그를 분리하는 단계;를 포함하는, 서브머지드 아크로를 통한 유가금속 회수방법을 제공한다. 본 발명의 다른 일 실시예는 i: 전자스크랩 및 저품위 동 슬러지를 혼합한 혼합물을 마련하는 단계; ii: 상기 i 단계의 혼합물과 플럭스를 서브머지드 아크로에 투입하고, 용융환원 처리하는 단계; 및 iii: 상기 ii 단계로 생성된 조금속 및 슬래그를 분리하는 단계;를 포함하는, 서브머지드 아크로를 통한 유가금속 회수방법을 제공한다.
