Abstract

There is an increasing need for developing new exploitation approaches for critical mineral resources. Europe among others has triggered important projects for securing their supply and lowering their extraction cost. In this context, in-situ leaching has received a growing interest, in particular with the consideration of the developing bio-leaching technologies. In this paper, we present the development of a geochemical model for simulating Copper extraction from Chalcocite-Covellite ore bodies. It is implemented with PhreeqC using streamline-based dual-porosity simulations. A coupling between PhreeqC and Gocad is proposed for investigating the effect of the geometry of the mineralization, the heterogeneity of rock properties, and the well design.
