Abstract

A study on the cementation for the recovery of tin with aluminium in the hydrochloric acid solution was carried out. Parameters, such as aluminium metal equivalent, pH, reaction time, reaction temperature and the concentration of chloride ions were investigated. The experimental results showed that the cementation rate of Sn(II) ions increased with increase of the addition amount of aluminium powders, temperature, pH and the concentration of chloride ions in hydrochloric acid solution. From the results, the optinum conditions for recovery of metallic tin by cementation with aluminium metal powders were proposed.

폐전자스크랩, 함주석 폐액 등에서 주석 성분을 회수하기 위한 기초 연구로 주석이 함유된 염산용액에서 알루미늄 분말을 이용한 치환반응에 대한 연구를 실시하였다. 주석이온의 치환 반응에 미칠 수 있는 용액의 pH, 알루미늄 분말 첨가량, 반응온도, 반응시간, 염소이온($Cl^-$) 농도, 불순물 농도 둥에 대해 고찰하였다. 치환실험 결과 알루미늄 분말의 첨가량. 반응온도, pH 및 염소이온 농도가 증가함에 따라 주석이거 치환속도가 증가함을 알 수 있었다. 이들 결과로부터 알루미늄 금속분말을 이용한 금속 주석의 치환 및 회수에 관한 최적 조건을 제시하였다.
