초록

인듐은 디스플레이 산업의 발전과 더불어 그 수요가 급격하게 증가하고 있으며 산업적 중요도도 높아 보조 공급원으로 부터의 회수기술 개발이 점점 관심을 얻고 있다. 폐 디스플레이 재활용을 위한 인듐 회수기술은 크게 해체분리, 선별농축 그리고 정제 공정으로 구성되어 있으며 목표하는 소재의 최종 순도에 따라 추가적으로 고도화 공정이 도입된다. 본 논문에서는 인듐 회수를 위해 적용되고 있는 기술에 대해서 소개하며 연구동향과 향후 전망 등에 고찰하였다.

Recovery of indium from secondary sources have been attracting over years not only because of increasing demand together with development of flat panel display industry but also industrial criticality of indium. Applied technology to recover indium for recycling of end-of-life FPD devices can be broadly divided into three major steps, disassembly or dismantling, enrichment or upgrading, and refining or purification. In addition, advanced technology such as zone-refining can be employed for ultra-high purity products. In this mini-review, we present currently applied technologies for recovery of indium and the outlook for total recycling of FDP devices.
