The Democratic Republic of Congo in particular contains large deposits of a mineral containing a mix of tantalum and niobium compounds, called columbite-tantalite, colloquially known as coltan. Profits from coltan mining have helped fund the opposing sides in the DRC's appalling civil war, which has killed more than 5 million people since 1998.
