Current Research Projects

NEMO Near-zero-waste recycling of low-grade sulphidic mining waste for critical-metal, mineral and construction raw-material production in a circular economy

This is an EU Horizon 2020 project conducted with 14 European partners. The NEMO project will lead to the unrestricted supply of critical raw materials (CRMs; Co, rare earths and Mg), valuable metals (Cu, Ni, Zn, and Sc), industrial minerals (Na2SO4, K2SO4 and MgSO4) and construction raw materials for cement and concrete production, originating from domestically available, but currently unexploited, sulfidic mining waste, and in this way substantially reduce Europe’s dependence on the imports of these vital raw materials.

Characterising metal-organic pollutants for remediation of mining environments

The aim of this project is to compare and contrast the source, speciation, transformation and stability of metal and organic pollutants in mining-affected environments in sites from China and the UK. I am working with scientists from the China University of Geosciences (Beijing) on this project, which is funded by the Royal Society

 

MERIDA Management of Environmental RIsks During and After mine closure

This project is supported by the Research Fund for Coal and Steel. The project aims to provide specific guidance on the issues that need to be considered when assessing the environmental impacts from coal mines at closure and post-closure stages, to establish an integrated risk assessment methdology and to provide a practical methodology that can be used to evaluate the risk of remediation measures.
