摘要：
The purpose of this study is to model the unsteady-state gold leaching behavior on a rotating disk in cyanide and air solutions. Employing a modified version of the kinetic expression established by Wadsworth and the accepted mass transport equations, computer simulations at different solution conditions were performed and compared to results obtained experimentally by other authors for similar systems. The simulations reproduce the effects of high solution pH, sulfide, Pb2+ and lime concentrations, as well as the change over from O-2 to CN- control with air pressure and cyanide concentration.
