Cobalt has become a key commodity for battery-powered vehicles and other electronic products. The Democratic Republic of Congo is the largest producer of cobalt. The so-called “Copperbelt” in the southeastern part of the country hosts most of the cobalt ore, mainly extracted through large-scale industrial mining but also through artisanal and small-scale mining activities by more than 100,000 miners. The sector faces numerous sustainability challenges within local supply chains, such as child work and other human rights violations. The Federal Institute of Geosciences and Natural Resources from Germany has now published a report, titled Mapping of the Artisanal Copper-Cobalt Mining Sector in the Provinces of Haut-Katanga and Lualaba in the Democratic Republic of the Congo, which analyzes the cobalt supply chain in the Congo. The focus of the mapping lay on the beginning of the supply chain, i.e. from the cobalt ore to the first domestic sale of production, which is often overlooked by Western consumers and users.
