抄録

The Anjing Hitam prospect hosts Zn-Pb orebodies that may trigger environmental issues during its future mining and smelting activities. Therefore, the understanding of mineralogical and geochemical characteristics of host rocks and orebodies in this prospect is important to reveal. Concentration of sulfur in the host rocks is controlled by pyrite. Pyrite and sphalerite control concentration of sulfur in pyrite-rich massive ore while sphalerite and galena control concentration of sulfur in sphalerite-rich massive ore. Concentrations of cadmium and arsenic are strongly controlled by sphalerite and galena, respectively. Future mining and smelting activities at the Anjing Hitam prospect may give rise to several environmental issues, such as acid mine drainage, soil acidification and degradation, trace element contamination and human health problems.
