Verbaan, B. and CRUNDWELL, F.K., An electrochemical model for the leaching of a sphalerite concentrate, Hydrometallurgy, 16 (1986) 345-359.

The leaching of a sphaleritic flotation concentrate in an acidic ferric sulphate solution is described by an electrochemical charge-transfer model in which the mineral surface potential is approximated by the solution redox potential for the ferrous--ferric redox couple. The oxidation of ferrous ions by dissolved oxygen is described by a model con- sistent with previously reported models, and the leaching of the sphalerite in the presence of dissolved iron and oxygen is described by the simultaneous integration of the two individual rate expressions.
