Streamline Simulation of Reactive Transport for Designing in-Situ Leaching of Copper with Insights from Column Experiments

 abstract = { In this contribution, we consider the reactive process for in-situ bio-leaching of Kupferschiefer Copper deposit as studied in the H2020 BIOMOre project. We present laboratory experiments that have been carried out for studying the efficiency of the leaching process with respect to various grain size fractions. One-dimensional dual porosity models are proposed for simulating the leaching process. Experimental results show that this model primarily relies on calibrating a volumetric ratio between advection dominated and diffusion dominated volumes and a first order exchange coefficient between these two fractions. We discuss the strategy for adapting this model to in- situ leaching of the Kupferschiefer Copper ore by similar leaching solutions circulating through large fracture sets between injector and producer wells. Preliminary results of reactive transport simulations on 3D reactive streamlines coupling PhreeqcRM to Gocad are finally presented. Introduction },
