— The global production of cobalt has increased over the period 2011–2018, as shown in Fig. 2. The data given in Fig. 3 indicates that the increase in global production has been sourced almost entirely from the DRC, which in 2018 produced about 60% of the world's cobalt (see Fig. 3).
— Africa holds approximately two-thirds of global cobalt reserves, around 30% of lithium and significant shares of other critical minerals, including manganese, copper and iron ore. Leading mineral markets on the continent include the Democratic Republic of Congo (DRC), which contributes over 70% of global cobalt production; Gabon, ranking …
