2021-9-13 · However, the Fe content of sphalerite in the Weilasituo Sn-Li-Rb deposit is not that high. The whole rock analysis shows that the alkali feldspar granite related to mineralization is extremely poor in Fe (0.13-0.44%) (Zhu et al., 2016). The iron content in granite is an important factor affecting the iron content of sphalerite in the tin deposits.
