But it’s no mystery why so …Jun 15, 2022 · Sphalerite (ZnS) has a sphalerite structure and a wurtzite structure (Balaz et al., 1992). The calculation is based on the sphalerite structure of which the space group is F-43 m, belonging to a cubic (equiaxed) crystal system (Chen and Chen, 2010a). The atoms in the unit cell present a face-centered cubic crystal structure. The coordination ... The concentration of Fe in sphalerite decreases, whereas the concentration of Zn increases gradually from Z-Sp to X-Sp2b (Fig. 6 a, b). The concentration of Fe in sphalerite is closely related to the color of the studied sphalerite crystals. The brown sphalerite (X-Sp2b) found in XOB has the lowest Fe concentration (av. (average) = 4.19 wt%).
