In 2013/14, Risk & Policy Analysts Ltd undertook the first global study on the socio-economic value of Manganese (Mn).  Based on a top-down analysis of the key supply chains for Mn, it outlined the economic importance of Mn ore and alloys in terms of their direct and indirect economic value, as well as their effects on employment (jobs and wages).  A recently published article in NeuroToxicology provides a summary of the results:  Clarke C & Upson S (2017):  A global portrait of the manganese industry – A socio-economic perspective, NeuroToxicology, Volume 58, pp 173-179.
