Market changes spurred by the 2010 Dodd-Frank law on conflict minerals have helped significantly reduce the involvement of armed groups in eastern Democratic Republic of Congo in the mines of three out of the four conflict minerals. The law, in addition to conflict minerals audit programs from the electronics industry and related reforms begun by African governments in the region but not yet fully implemented, has made it much less economically viable for armed groups and Congo’s army to mine tin, tantalum, and tungsten...However, artisanally mined gold continues to fund armed commanders. Further reforms are needed to address conflict gold and close loopholes on the other minerals.
