| Abstract: |
In this paper a two-dimensional solute transport model is considered to simulate the leaching of copper ore tailing
using sulfuric acid as the leaching agent. The mathematical model consists in a system of differential equations: two
diffusion–convection-reaction equations with Neumann boundary conditions, and one ordinary differential equation.
The numerical scheme consists in a combination of finite volume and finite element methods. A Godunov scheme is
used for the convection term and an P1-FEM for the diffusion term. The convergence analysis is based on standard
compactness results in L2. Some numerical examples illustrate the effectiveness of the scheme. |
