MULTI-SCALE INVESTIGATION OF URANIUM ATTENUATION BY ARSENIC AT AN ABANDONED URANIUM MINE, SOUTH TERRAS
Corkhill, C.L., D.E. Crean, D.J. Bailey, C. Makepeace, M.C. Stennett, R. Tappero, D. Grolimund, and N.C. Hyatt. Nature Materials Degradation 1:19(2017)

An international team led by the University of Sheffield has discovered that the toxic element arsenic prevents uranium at the abandoned South Terras uranium mine in Cornwall, England, from migrating into surface water and groundwater. Ore extraction processes and natural weathering of rock at the South Terras mine led to the proliferation of other elements during degradation, particularly arsenic and beryllium, which were found in significant concentrations. The arsenic and uranium have formed the highly insoluble secondary mineral metazeunerite. This paper is Open Access at https://www.nature.com/articles/s41529-017-0019-9.
