Short summary
Common energy dispersive methods cannot accurately analyze low concentrations of cobalt in pyrite due to the overlapping of cobalt and iron peaks. The Raman method, on the other hand, has been shown to be very sensitive to a trace amount of cobalt. In addition, it can be applied on a rough surface, does not require a vacuum chamber, and operates with a laser instead of X-rays. Thus, Raman has the potential to be used as an assaying tool for Co-bearing pyrite.
