The appetite for electric cars is driving a boom in small-scale cobalt production in the Democratic Republic of Congo, where some mines have been found to be dangerous and employ child labor.

Production from so-called artisanal mines probably rose by at least half last year, according to the estimates of officials at three of the biggest international suppliers of the metal, who asked not to be named because they’re not authorized to speak on the matter. State-owned miner Gecamines estimates artisanal output accounted for as much as a quarter of the country’s total production in 2017.
