Clinton praises ‘conflict mineral’ provision in financial overhaul

The law mirrors a bill introduced by Sen. Sam Brownback (R-Kan.) requiring companies to make annual Securities and Exchange Commission disclosures about what materials they use and the origin of certain minerals.

The Enough Project, an anti-genocide group, directly links Congo violence to the largest 21 technology companies. A handful protested the opening of the Apple store in Georgetown last month.

The bill specifically targets gold, tin, tungsten and tantalum. Tantalum stores electricity in cell phones, tungsten makes cell phones vibrate, tin is used in circuit boards, and gold is used to coat wiring, according to Enough Project’s Jon Prendergast.

Some electronics companies have expressed concern that the bill will be tough to comply with, as minerals origins can be hard to trace.
