In Congo’s sun-scorched and dusty south, thousands of miners scour underground tunnels hunting for cobalt. Many of them work by hand. That’s why they are known as creuseurs — French for diggers.
They don’t use power tools. They don’t wear face masks and often no gloves. They do it because they live in one of the poorest countries in the world, and cobalt is valuable. The mineral is essential for the lithium-ion batteries found in smartphones and many electric vehicles. Most of the world’s cobalt supply comes from the Congo region. These cobalt-laden chunks of rock leave the country destined for refineries in Europe and China, where they enter the complex supply chains of some of the largest technology and automotive firms.
Creuseurs know their work is physically dangerous. Death and injury from tunnel collapses are not uncommon. Children sometimes join their older brothers and fathers in the mines
