A black market for coltan â a strategically important mineral used in an array of electronic devices â has emerged in the Amazon jungles that cover the border area between Colombia, Venezuela and Brazil. In Venezuela and most of Colombia coltan mining is illegal, yet small-scale miners and buyers are plentiful.
The extraction of coltan contributes to maintaining one of the bloodiest armed conflicts in Africa, which has led to more than five million deaths, massive displacements of the population, and the rape of 300,000 women in the last 15 years, according to human rights organisations.
