This project is offered as a Stellenbosch University-Coventry University Cotutelle PhD, providing a unique international research environment that combines expertise in sustainable mining, resource recovery, electrochemical engineering, and green hydrogen technologies. The successful candidate will benefit from joint supervision, access to world-class research facilities at both institutions, and opportunities to develop an international research profile through collaborative activities and knowledge exchange.
The student will be based primarily within the Department of Chemical Engineering at Stellenbosch University, South Africa, working under the supervision of Professor Prathieka Naidoo, Chair in Green Hydrogen Integration and Transition. The research will focus on developing innovative strategies for the remediation and valorisation of acid mine drainage (AMD), one of the most significant environmental challenges associated with mining activities worldwide. AMD contains elevated concentrations of dissolved metals, sulphates, and other contaminants, but also represents an underutilised source of valuable resources.
The project will investigate approaches for the selective recovery of critical metals from AMD through precipitation and treatment processes, generating a treated low-quality water stream suitable for subsequent electrochemical utilisation. Attention will be given to recovering strategically important metals and improving the overall sustainability and economic viability of AMD treatment systems. Building upon this resource recovery platform, the project will explore the use of reclaimed low-quality water as a feedstock for hydrogen production using robust electrochemical systems capable of operating under non-ideal water quality conditions. The research will examine how residual contaminants may be utilised within alternative anodic oxidation pathways, enabling simultaneous pollutant remediation and clean hydrogen generation. This integrated approach aims to reduce treatment costs, improve resource efficiency, and contribute to the development of circular economy solutions for the mining sector.
The placement will provide valuable training in electrochemical testing, reactor design and hydrogen system operation, while facilitating the transfer of flow-cell electrolysis expertise between Coventry University and Stellenbosch University. The student will also engage with researchers working across hydrogen production, electrochemical engineering, and sustainable energy systems, strengthening international collaboration and supporting the development of future joint research initiatives.
Overall, the project offers an exciting opportunity to contribute to cutting-edge research at the interface of environmental remediation, critical materials recovery, and green hydrogen production, while developing the technical, professional, and international skills required for a successful research career.
This PhD is a cotutelle PhD between Coventry University (UK) and Stellenbosch University (South Africa). The successful candidate will primarily be based in Stellenbosch, but will be required to undertake a significant period of study in Coventry as a requirement of the PhD.
