Abstract
The dissolution of sphalerite in aqueous sulfuric acid is studied in the presence of oxygen in an autoclave at 200 C. In the presence of oxygen, and an oxidized hydrogen sulfide there’s formation of elemental sulphur and sulfuric acid. The kinetic of the reaction is studied as a function of the mass of zinc sulfide, the concentration of sulfuric acid, the oxygen partial pressure and temperature. A kinetic model taking into account those factors is hence proposed. On the other hand, the role of hydrogen sulfide on the progress of dissolution is highlighted.
