While the US government hasn't issued an outright ban against the use of 'conflict minerals' coming from the Congo, it has passed a law that will require companies who use them to tell all of us when our gadgets have been paid for (in part) with blood. Looks like Apple and Intel weren't too keen on the bad PR that would come from such disclosures, and joined the Electronic Industry Citizenship Coalition and its Conflict-Free Smelter program. The program requires mineral processing plants either prove that they don't fund the ongoing hostilities in central Africa or peddle their war-supporting wares elsewhere. For now, that means that the folks in Cupertino and Santa Clara will have to find other sources for the three Ts (tungsten, tin, and tantalum) needed to sate our technological appetites.
