Abstract

Electrokinetic in situ leaching (EK-ISL) is a novel mining technique that uses an electric field to move a lixiviant through intact, in-situ ore bearing rocks from which element(s) of interest are leached, towards an extraction zone. This thesis investigates the in-principle feasibility of EK-ISL using laboratory-scale experiments with both synthetic ore material and with intact gold and copper ore samples. Reactive transport modelling is used to support the interpretation of the experimental data. The thesis provides a proof of concept for EK-ISL, suggesting that the technique could become an economic and environmentally friendly alternative to current mining practices.
