Abstract：The dissolubility and surface properties of chalcopyrite were studied in different mechanical stirring time and different pH value solution under argon and oxygen atmosphere by ICP-MS, AFM and XPS analysis. Besides, the XRD diffraction pattern and crystal structure of chalcopyrite and its dissolution model in aqueous solution were established. The laboratory results indicate that the relationship between copper and iron concentrations in solution and time in pure water can be derived as the equation c=ksat+b. The lower pH value makes it easier for chalcopyrite to dissolve, and that the surface oxidation is slow has minor effect on the dissolubility. In pure water, the dissolution of chalcopyrite has little influence on the effective specific surface area, and the dissolution is controlled by surface chemical reaction under acidic conditions. After long time dissolution, the surface of the chalcopyrite assumes copper-rich state relative to iron and the surface roughness and lattice imperfections increase.
