초록

폐 젤리충진 통신케이블로부터 고순도 구리회수를 위하여 실리콘계 및 톨루엔계 합성 열매유와 폐식용유를 사용하여 적용성을 평가하였다. 실리콘계 오일의 경우 모든 조건에서 분리효율이 낮은 반면, 톨루엔계 오일 및 폐식용유의 경우 처리온도 및 시간을 조절함에 따라 높은 분리효율을 얻을 수 있었다. 폐식용유를 사용하는 50 kg급 밀폐형 대용량 설비를 이용하여 300 ℃에서 60 min 이상 처리할 경우 99.2% 이상의 고순도 구리와이어를 100% 회수할 수 있었다.

We examined and compared the feasibility of vegetable oils with synthetic thermal conductive oils to recover highly purified copper metal from waste jelly-filled communication cables. While polydimethylsiloxane shows relatively poor separation efficiency under entire operating conditions, dibenzyltoluene and waste vegetable oil show the high separation efficiency if the appropriate operating temperature and time were given. By running 50 kg-class equipment with waste vegetable oils, we obtained 100% copper metal recovery with 99.2% purity at 300 ℃ for 60 min.
