Abstract

Electrical pulse disintegration(ED) is known as an efficient technology for recovering valuable resources by inducing dielectric breakdown in solids to separate mineral interfaces in ores among the crushing technologies by high voltage discharge. In this study, ED crushing experiment and mechanical crushing experiment of sulfide minerals were performed, and SEM analysis and Microfocus X-Ray CT of the crushed product were performed in order to analyze the disintegration characteristics of zinc minerals exist in the sulfide minerals by the shock wave generated in the solid by high voltage discharge.

고전압 방전에 의한 파분쇄기술 중 ED(Electrical pulse Disintegration)는 고체 내 절연파괴를 유도하여 고체 내 취약한 경계면을 분리하여 유가자원을 분리·회수하는 고효율 자원처리 기술로 알려져 있다. 본 연구에서는 고전압 방전에 의하여 고체 내 발생한 충격파가 황화광물 내 존재하는 아연광물의 단체분리특성을 분석하기 위하여, ED분쇄실험과 기계식 분쇄실험을 수행하고 분쇄산물에 대한 SEM-BSE 분석과 Microfocus X-Ray CT 분석을 수행하여 단체분리도를 비교하였다.
