Conflict minerals, specifically tungsten, tantalum, tin, and gold, are sourced from regions in the Democratic Republic of the Congo under conditions of armed conflict and human rights abuses. The Dodd-Frank Act of 2010 mandates that companies disclose the sources of these minerals in their supply chains to promote ethical mining practices. Ongoing international efforts, including a UN pilot project, aim to regulate mineral trading to mitigate the humanitarian impact associated with these resources.
