Conflict minerals are minerals mined in conditions of armed conflict and human rights abuses, notably in the eastern provinces of the Democratic Republic of the Congo, by the Congolese National Army and various armed rebel groups, including the Democratic Forces for the Liberation of Rwanda. The profits from the sale of these minerals finance continued fighting in the Second Congo War, and control of lucrative mines becomes a focus of the fighting as well. The most commonly mined minerals are cassiterite, wolframite, coltan, and gold, which are extracted from the Eastern Congo, and passed through a variety of intermediaries before being purchased by multinational electronics companies. These minerals are essential in the manufacture of a variety of devices, like mobile phones, laptops, and MP3 players.
