Abstract

This paper presents a comprehensive review of recent research trends in hydrometallurgical processes for the recovery of zinc from zinc-containing industrial byproducts. In particular, we analyze the efficiency and methodology of various inorganic and organic acid leaching techniques for the selective recovery of zinc from electric arc furnace dust and zinc smelting dust. Furthermore, we discuss methods for separating coexisting iron impurities. Ultimately, this review aims to serve as an important reference material, contributing to the advancement and commercialization of recycling technologies for diverse zinc-containing industrial byproducts.

Keywords

본 논문은 아연 함유 산업부산물에서 아연을 회수하기 위한 습식공정에 대하여 최근까지의 연구 동향을 종합적으로 고찰하였다. 특히, 전기로 제강 분진인 EAFD(Electric Arc Furnace Dust) 및 아연 소광 분진(Zinc Smelting Dust, ZSD)에서 아연을 선택적으로 회수하는 다양한 유·무기산을 이용한 침출 방법과 그 효율을 분석하였다. 나아가, 본 연구는 불순물로 존재하는 철 성분에 대한 분리 방법에 대하여 논의하였으며, 최종적으로 다양한 아연 함유 산업부산물의 재활용 기술 발전과 실용화에 기여할 중요한 참고 자료로서 활용되기를 기대한다.
