Nowadays, deep in situ biomining is considered as a viable technic (about cost and environement) to extract metals from low-grade rocks and below the land surface [1]. In this framework, the BioMore project aims at evaluating the rates of copper recovery with this technic. That is why, a high pressure set up was designed in this work to reproduce deep in situ leaching process. The aim is to characterize the (bio)geochemical mechanisms implied.
