Last month, we shared with you a useful infographic from our friends at Silicon Expert Technologies that illustrated the impact of the SEC rules on conflict minerals (See Infographic: Conflict Minerals Trail).
Here's one that breaks down where 3TG is coming from and who's affected.

Nice graphic but still understates the problem as vast majority of the Rwandan tantalum is DRC tantalum and i suspect a lot of the trade goes under the radar especially with gold which is very easy to smuggle. Also since 2009 Australian Mozambican and American production tantalum has run into trouble.

There is likely to be supply squeeze over tin in the coming years as well and the price is likely to be a lot higher in the future.

@Brain, thanks for the post. Very informative. The graph clearly shows that most of the conflict mineral originates from DRC. I think UN should play a larger role in maintaining peace in DRC so that the money earned through mining is not spent on war.
