Most of us have heard of blood, or conflict diamonds. The Kimberly Process made great strides in certifying conflict-free diamonds, and eliminating blood diamonds. But did you know there are other conflict minerals? I didn't. When I researched conflict diamonds for Exit Strategy, I found a wealth of material. But nothing on coltan, which is used to create tantalum. Tantalum capacitors are used in our cell phones, computers and many other electronics.
