Apple today issued its first ever conflict minerals report, a full breakdown of where it gets key materials that end up in its phones, tablets, and computers, but that can be mined in politically unstable countries. In it, the company says 21 of the 205 smelters it used in 2013 got those minerals from the Democratic Republic of the Congo (DRC) or adjoining countries, and that four of those had not been certified as conflict-free. Apple added that it commissioned its own audits of those four companies and found no reasonable basis that they were financing armed groups. The move is meant to put pressure on companies and governments to crack down on conflict minerals, but its also drawn controversy for threatening companies to pull their business from those regions entirely.
