闪锌矿中的铁包括结构铁和以六配位形式存在的出溶铁，本文提出了应用Ｘ射线衍射测定闪锌矿中结构铁质量分数的新方法。通过对一系列不同结构铁质量分数闪锌矿的主要衍射线强度的理论计算发现，随着闪锌矿中结构铁质量分数的增加，其主要衍射线强度比值Ｉ（００２）／Ｉ（１１１），Ｉ（１３３）／Ｉ（１１１），Ｉ（１３３）／Ｉ（１１３）和Ｉ（００２）／Ｉ（１１３）逐渐递减，尤以Ｉ（００２）／Ｉ（１１３）比值递减最为明显，两者几乎呈线性负相关。利用该原理对国内典型铅锌矿床中闪锌矿的结构铁质量分数进行了测定，并与化学分析结果进行对比。
Iron in sphalerite includes structural iron and iron in the form of hexacoordinated iron. A new method for the determination of structural iron mass fraction in sphalerite by X-ray diffraction is proposed in this paper. Based on the theoretical calculation of the main diffraction line intensity of a series of sphalerite with different structures, it is found that the ratio of the main diffraction line intensity (I (002) / I (111)) increases with the increase of the mass fraction of structural iron in the sphalerite. , I (133) / I (111), I (133) / I (113) and I (002) / I (113) decreased gradually with the decreasing ratio of I (002) / I Almost linearly negative correlation. Using this principle, the structural iron content of sphalerite in typical lead-zinc deposits in China was measured and compared with the results of chemical analysis.
