This is because the sulfur-containing metal minerals are mainly pyrite (FeS2), chalcopyrite (CuFeS2), sphalerite (ZnS), and galena (PbS) (José et al., 2005).
This is because the main metal minerals containing sulfur are yellow iron ore (FeS2), brass (CuFeS2), flash zinc (ZnS), and square lead (PbS) (José et al., 2005).
This is because the sulfur-bearing metal minerals are mainly pyrite (FeS2), copper copper (CuFeS2), zinc blende (ZnS), galena (PBS) (Jos é et al., 2005).<br>
