초록
폐콘덴서로부터 탄탈륨 음극을 회수하기 위하여 물리적 선별과, 염소가스와 사염화탄소를 이용한 기초 염화반응에 관한 연구를 수행하였다. Stamp mill을 이용한 파쇄, 요동테이블에서의 습식 비중선별 그리고 공기 분급을 통하여 탄탈륨 음극을 98% 회수할 수 있었다. 염소가스를 이용한 TGA분석에서 탄탈륨 음극의 최대 무게 감소는 60%였고, 사염화탄소에 의한 탄탈륨 음극의 염화반응은 탄탈륨 음극을 산화탄탈륨으로 변환한 후가 반응율이 높았다.
Abstract
For recycling of tantalum from obsolete condenser, physical separations and chlorination of tantalum scraps with Cl2 and CCl4 were investigated. The recovery ratio of tantalum from obsolete condenser was 98% by using a multidisciplinary process of crushing by stamp mill, wet gravity separation by the shaking table, and air classification. In the chlorination reaction of non-oxidized Ta anode with Cl2, the highest weight loss ratio is at least 60%, while in the chlorination reaction of Ta anode with CCl4, the reaction rate for the oxidized Ta anode is faster than that of the non-oxidized Ta anode.
