critical metals [9]. The processing of antimony ores and the production of antimony metal is also concentrated in China, due to its high smelting capacity. Most of the antimony industry in Europe and the U.S.A. is therefore dependent on the import of Chinese antimony metal and is focused on the production of high-purity products and applications.

We still lack understanding of the environmental behavior and geochemical process of antimony in soil and water at the atomic level. One of the most critical problems is the microstructure, existence form and complex reaction mechanism of antimony at the interface of natural minerals (Zhang et al., 2020). Understanding these basic information ...
