The Democratic Republic of Congo (DRC) is one of the most resource-rich countries in the world — its untapped deposits of raw minerals are estimated to be worth in excess of $24 trillion.

The DRC is most known for its cobalt mining — about 70% of the world’s cobalt is mined there, often by artisanal miners and even children. The trade has been linked by researchers to violence, substance abuse and food-water insecurity, but much less is known about its coltan mining sector.

Many cell phones and other electronic devices contain tantalum, which comes from the ore coltan (columbite-tantalite).

In 2021, the African country’s coltan production was estimated at 700 tonnes, making the DRC the world’s largest coltan producer.

Activists, journalists and scholars have found a relationship between coltan exploitation and large-scale environmental degradation, human rights abuses, violence and death, the Conversation reported.
