The chemical and physical properties of mineral surface and its research tools are introduced. The current situation of surface reactions such as surface oxidation of sulfide minerals, surface adsorption of clay minerals, and surface dissolution of silicate minerals and carbonate minerals is summarized. In particular, the recent progress on the surface reactions of pyrite, including the reaction kinetics of pyrite oxidation, the indicative significance of pyrite on pyrite surfaces, the migration of sulfur and heavy metal elements in pyrite oxidation and its environmental effects, was reported. The surface reaction mechanism and kinetics of the above minerals have a wide range of applications in environmental assessment and treatment, research on global climate change and other aspects.
