More than 200 people were killed this week in a collapse at the Rubaya coltan mine in eastern Democratic Republic of Congo, Lumumba Kambere Muyisa, spokesperson for the rebel-appointed governor of the province where the mine is located, told Reuters on Friday.
Rubaya produces around 15 percent of the world’s coltan, which is processed into tantalum, a heat-resistant metal that is in high demand by makers of mobile phones, computers, aerospace components and gas turbines. The site, where locals dig manually for a few dollars per day, has been under the control of the AFC/M23 rebel group since 2024.
