An axisymmetric modelModel is developed to simulate water and solute transport in a column leachingLeaching system, incorporating advection, dispersion, adsorptionAdsorption, and chemical reactions. This study extends the modelModel to include ferric leachingFerric leaching of chalcociteChalcocite through a two-stage reaction process using experimentally derived parameters. The first stage follows a Type I–III hybrid leachingLeaching mechanism, while the second stage is governed by a Type I–II hybrid mechanism. Each captures key aspects of ferricFerric ion interaction with chalcociteChalcocite. The modelModel is validated through a stepwise approach, including water transport, solute transport, and individual reaction stages. Simulations reveal spatial and temporal distributionsDistribution of ferricFerric ions, chalcociteChalcocite-I, chalcociteChalcocite-II, and copperCopper concentrations. Results show that ferricFerric is consumed rapidly in the first stage and more slowly in the second, affecting copper recoveryCopper recovery. The modelModel captures key transport and reaction behaviors consistent with expected leachingLeaching processes and provides a foundation for future integrationIntegration of experimental data and extended simulations.
