"If you are reading this on a smartphone, then you are probably holding in your palm the conflict minerals that have sent the biggest manufacturing trade group in the U.S. into a court battle with the Securities and Exchange Commission. At stake in this battle between the National Association of Manufacturers and the government is whether consumers will know the potentially blood-soaked origins of the products they use every day and who gets to craft rules for multinational corporations—Congress or the business itself. ... These minerals are tantalum (used in cellphones, DVD players, laptops, hard drives, and gaming devices), tungsten, tin, and gold, if they are mined in the Democratic Republic of Congo and surrounding countries including Rwanda, where the mineral trade has fueled bloody conflicts. The rule requiring disclosure of conflict minerals will go into effect in 2014. Congress included it in Dodd-Frank out of concern for what is known as the “resource curse”—the phenomenon wherein poor counties with the greatest natural resources end up with the most corrupt and repressive governments. The money earned from selling the natural resources props up these harsh regimes and funds violence against their citizens and neighbors."
