Abstract
In this paper we describe error estimates for a finite element approximation to partial differential systems describing two-phase immiscible flows in porous media, with applications to heap leaching of copper ores. These approximations are based on mixed finite element (MFE) methods for the pressure and velocity and finite volume (FV) for the saturation. The fluids are considered incompressible. Numerical results for heap leaching simulation are presented.
