Dr Paul F. Schofield is leading the part of the CoG3 project that focuses on describing and characterising new ore types, with an aim of developing new ways of extracting cobalt (Co). He reports back on a visit to Diamond Light Source.
In early September the Museum CoG3 team met with Prof Fred Mosselmans, a fellow member of the CoG3 consortium from Diamond Light Source. The team hoped to use Diamond’s facilities to study how cobalt is incorporated into the minerals of the Nkamouna cobalt-nickel laterite deposit in Cameroon.
The Diamond Light Source facility provides very intense, high-brightness beams of X-rays that are focused to produce powerful microscopes. Not only do these microscopes allow us to image the distribution of cobalt in natural materials with nanometre scale resolution, but they also enable us to measure how the cobalt atoms are actually bound into the atomic structure of their hosting minerals.
Researcher Dr Agnieszka Dybowska describes a recent visit to Diamond Light Source, the UK’s national synchrotron science facility, during which the CoG3 team completed their first detailed spectroscopic analysis of laterite samples.
On Thursday 28 April we headed to Diamond Light Source in Oxfordshire, hoping to carry out atomic scale analysis of a sample from the Shevchenko laterite deposit in Kazakhstan – one of the samples we’re investigating as a potential new source of cobalt.
For some of us this was the first visit to a synchrotron facility, and definitely a great experience!
