Uranium is often symbiotic with pyrite in natural uranium ore, and there is an interaction between uranium and pyrite. Organics and microbes in the environment may also have some influence on this symbiosis. In this paper, cyclic voltammetry (CV) was used to study the change of uranium valence state and electron transfer number in pyrite and U(VI) system. The results showed that pyrite could spontaneously reduce U(VI) to U(V) and U(IV). It was also found that humic acid (HA) inhibited the reduction of uranium by pyrite, while thiobacillus ferrooxidans (TF) could promote the reduction process. Photoelectron spectroscopy studies showed that Fe²⁺ and S^- in pyrite both play a role in the reduction of U(VI). The mechanism of reduction and enrichment of uranium in pyrite is studied from the microscopic perspectives of electron and ion, and the symbiosis of uranium and pyrite in natural uranium ore is explained, which provides a new basis for the theory of uranium mineralization. It provides a new theoretical basis for the application of pyrite in environmental pollution restoration and the degree of influence of the surrounding environment.
