Working with colleagues Ali Ford<\/a>, Oliver Heidrich<\/a>, and David Manning<\/a> on various papers and proposals, we have started to pull together a Sankey diagram of the reported tonnages of cobalt in 2012 through various processing stages within its life cycle. The orange and green colours denote the quantities of cobalt reported by the respective importing or exporting countries, but we have aggregated to the continent level. This information was extracted from the UN COMTRADE database and linked to eSankey! software via an intermediate Excel spreadsheet. The good thing about this approach is that by updating the spreadsheet with new values e.g. for different years etc, or for different elements\/commodities\/products, we can auto-generate (ish) the Sankey diagram.<\/p>\n

Going even further, Ali reproduced the data above at the country-level, across the same three stages i.e. Mining->Refining; Refining->Manufacturing; Manufacturing->Use, but using only the import flow data for now (matches orange flows above)<\/p>\n
