An interesting article to say the least, seems that former areas exploited once by Western powers are they themselves doing the same to countries that are in a position they once were.
With regards to Minnesota, there are a number of active "sand mines" down here in Georgia, mostly exploiting old deposits when the ocean was much further inland. I remember visiting one while going for Pecans. They are used for everything from providing construction sand, braking sand (think trains), to extracting other valuable minerals like zirconium and titanium.
