Abstract

The objective of this study was to research the mineralogical characteristics and removal of heavy metals of tailings from Gum-poong mine. From the result of mineralogical analysis, there are several sulphide minerals such as chalcocite, aresenopyrite, pyrite, sphalerite and galena. Cd and Zn have a good positive correlation from the statistical relation between Cd and other heavy metals(Cu, Pb, Zn). Residual heavy metals(As, Cd, Cu, Pb, Zn) from the Gum-poong tailings were removed under the warning criteria from the result of froth flotation with K.A.X.(Potassium Amyl Xanthate) and Aerofloat 211.

본 연구의 목적은 금풍광산 광물찌꺼기 내 중금속의 광물학적 특성을 조사하고, 중금속 제거를 위한 부유선별 실험을 하였다. 광물학적 분석 결과, 휘동석, 유비철석, 황철석, 섬아연석, 방연석 등 황화광물이 존재하였다. 카드뮴과 다른 중금속(Cu, Pb, Zn)의 상관관계를 살펴보면 Cd는 Zn과 좋은 양의 상관관계를 가졌다. K.A.X.(Potassium Amyl Xanthate)와 Aerofloat 211을 포수제로 사용한 부유선별 실험 결과 광물찌꺼기 내 잔류 중금속(As, Cd, Cu, Pb, Zn)의 농도가 토양오염기준치를 만족하는 결과를 얻었다.
