Removal and recovery of vanadium from alkaline steel slag leachates with anion exchange resins (2016)
Journal Article
Gomes, H. I., Jones, A., Rogerson, M., Greenway, G. M., Lisbona, D. F., Burke, I. T., & Mayes, W. M. (2017). Removal and recovery of vanadium from alkaline steel slag leachates with anion exchange resins. Journal of environmental management, 187, 384-392. https://doi.org/10.1016/j.jenvman.2016.10.063

© 2016 The Author(s) Leachable vanadium (V) from steel production residues poses a potential environmental hazard due to its mobility and toxicity under the highly alkaline pH conditions that characterise these leachates. This work aims to test the e... Read More about Removal and recovery of vanadium from alkaline steel slag leachates with anion exchange resins.

Timing and causes of North African wet phases during the last glacial period and implications for modern human migration (2016)
Journal Article
Hoffmann, D. L., Rogerson, M., Spötl, C., Luetscher, M., Vance, D., Osborne, A. H., …Moseley, G. E. (2016). Timing and causes of North African wet phases during the last glacial period and implications for modern human migration. Scientific reports, 6(1), Article ARTN 36367. https://doi.org/10.1038/srep36367

We present the first speleothem-derived central North Africa rainfall record for the last glacial period. The record reveals three main wet periods at 65-61 ka, 52.5-50.5 ka and 37.5-33 ka that lead obliquity maxima and precession minima. We find add...

Vanadium removal and recovery from bauxite residue leachates by ion exchange (2016)
Journal Article
Gomes, H. I., Jones, A., Rogerson, M., Burke, I. T., & Mayes, W. M. (2016). Vanadium removal and recovery from bauxite residue leachates by ion exchange. Environmental science and pollution research, 23(22), 23034-23042. https://doi.org/10.1007/s11356-016-7514-3

Bauxite residue is an important by-product of the alumina industry, and current management practices do not allow their full valorisation, especially with regard to the recovery of critical metals. This work aims to test the efficiency of ion exchang... Read More about Vanadium removal and recovery from bauxite residue leachates by ion exchange.

Growing spherulitic calcite grains in saline, hyperalkaline lakes: experimental evaluation of the effects of Mg-clays and organic acids (2016)
Journal Article
Mercedes-Martín, R., Rogerson, M., Brasier, A., Vonhof, H., Prior, T., Fellows, S., …Pedley, H. (2016). Growing spherulitic calcite grains in saline, hyperalkaline lakes: experimental evaluation of the effects of Mg-clays and organic acids. Sedimentary Geology, 335, 93-102. https://doi.org/10.1016/j.sedgeo.2016.02.008

The origin of spherical-radial calcite bodies - spherulites - in sublacustrine, hyperalkaline and saline systems is unclear, and therefore their palaeoenvironmental significance as allochems is disputed. Here, we experimentally investigate two hypoth...
