초록

주석을 함유한 폐기물에서 고순도 주석을 회수하는 기술을 개발하기 위해 주석오니의 환원 제련 및 전해정련에 대해 연구하였다. 2단계의 건식제련을 통해 주석오니에 함유된 주석산화물을 환원시켜 92.7%의 주석을 회수하였다. 또한 건식공정으로 회수한 조주석을 전해정련시켜 순도를 99.87%까지 증가시켰다. 본 연구결과는 국내에서 발생하는 폐자원으로부터 주석을 회수하여 국내 주석 소비량의 일부를 대체할 수 있는 상용화기술의 토대가 될 수 있다.

In order to develop a technology for the recovery of pure tin from the Sn containing industrial wastes (SIWs), a process consisted of high temperature reduction and electrorefining was investigated. The tin which exists as oxide in SIWs was successfully reduced by two consecutive high temperature treatments and 92.7% of the tin was recovered. The purity of the tin thus obtained was increased to 99.87% by electrorefining. By applying the results obtained in this work, a commercial process can be developed to produce pure tin metals from domestic spent resources, which can reduce the amount of tin imported from abroad.
