Chemical composition: Sphalerite is a naturally occurring mineral that belongs to the class of sulfide minerals, and its chemical composition is relatively simple. It is a zinc sulfide mineral with the chemical formula ZnS, which means that it consists of zinc and sulfur atoms in a 1:1 ratio.Sphalerite is the predominant ore mineral of the Zhongyuku (Z-Sp), Yindonggou (Y-Sp), and Xigou (X-Sp) ore blocks in the Chitudian deposit. Five types of sphalerite (Z-Sp, Y-Sp1, Y-Sp2, X-Sp1, and X-Sp2) are distinguished in this deposit, based on petrographic observations and sample locations.Galena, also called lead glance, is the natural mineral form of lead(II) sulfide (PbS).

Galena is one of the most abundant and widely distributed sulfide minerals.It crystallizes in the cubic crystal system often showing octahedral forms. It is often associated with the minerals sphalerite, calcite and fluorite.Sphalerite, the dominant ore-mineral of Zn, is mainly composed of Zn and S, but Fe concentrations up to 15 wt% are observed due to substitution for Zn, or as inclusions (Cook et al., 2009). In addition, minor and trace elements (e.g., Cd, Mn, As, Ag, Cu, Co) are also hosted in sphalerite in a wide range of concentrations (Cook et al., 2009).

Zinc sulfide (or zinc sulphide) is an inorganic compound with the chemical formula of ZnS. This is the main form of zinc found in nature, where it mainly occurs as the mineral sphalerite. Although this mineral is usually black because of various impurities, the pure material is white, and it is widely used as a pigment.
