Abstract	The dissolution mechanism of hemimorphite in NH$_{3}$-(NH$_{4}$)$_{2}$SO$_{4}$-H$_{2}$O system at 298.15 K was investigated by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) analysis. The results show that hemimorphite is soluble in NH$_{3}$-(NH$_{4}$)$_{2}$SO$_{4}$-H$_{2}$O system and its residue exists in the form of an amorphous SiO$_{2}$ layer on the hemimorphite surface. The XPS data also indicate that the Si 2p3/2 and O 1s spectra of the hemimorphite are broadened and shift to higher binding energies and their binding energies are closer to silica with an increase of total ammonia and time. Solubility of hemimorphite in NH$_{3}$-(NH$_{4}$)$_{2}$SO$_{4}$-H$_{2}$O system was measured by means of isothermal solution method at 298.15 K based on the study of the dissolution mechanism of hemimorphite. The results show that the solubility of zinc in solution increases firstly and then decreases with the increase of c $_{T}$(NH$_{3}$) (total ammonia concentration) at different NH$_{3}$/NH$_{4}$ $^{+}$ ratios. The solubility of silicon in solution decreases from 0.0334 mol/kg in c $_{T}$(NH$_{3}$)=4.1245 mol/kg NH$_{3}$-(NH$_{4}$)$_{2}$SO$_{4}$-H$_{2}$O solution to 0.0046 mol/kg in c $_{T}$(NH$_{3}$)=7.6035 mol/kg NH$_{3}$-(NH$_{4}$)$_{2}$SO$_{4}$-H$_{2}$O solution.
