Abstract

The Zisman plot was prepared based on the contact angles of sulfide minerals determined using the sessile drop method. The estimated critical surface tension of wetting (ϓcw) was slightly smaller than that of floating (ϓcf), estimated based on natural floatability. However, the order of the ϓcf values, i.e. pyrite > sphalerite > galena > chalcopyrite, estimated from natural floatability, corresponded to that of the ϓcw values obtained from the Zisman plot using the contact angles . Thus, research on critical surface tension using the above-mentioned results should provide meaningful material for the flotation separation of complex sulfide minerals.

황화광물의 sessile drop 접촉각 측정결과로부터 Zisman plot을 구성하여 예측한 젖음 임계표면장력(ϓcw)은 황화광물 부선의 자연부유도 결과로부터 예측한 부선 임계표면장력(ϓcf)보다는 약간 작은 값을 가진다. 그러나 자연부유도로부터 유도된 황화광물의 ϓcf 값의 크기순서는 황철석 > 섬아연석 > 방연석 > 황동석 순으로 이는 접촉각을 이용하여 Zisman plot에 의해 유도된 황화광물의 ϓcw값의 크기순서와 일치하였다. 이와 같은 결과를 통해 임계표면장력 연구는 복합 황화광의 부유선별에 있어 의미 있는 자료로 활용될 수 있을 것으로 기대된다.
