Abstract
A kinetic gold leaching model, based on the well-known shrinking core model, is presented in this work. The model considers the effects of internal diffusion, surface reaction and unreacted amount of gold in the concentrate particle during leaching. The model parameters are estimated by minimization of mismatching between experimental data and results of numerical computation of kinetic model made by using ReactOp software.
