Ever wonder what mineral resources are mined in the United States?
There are so many things that we use day-to-day that are mined. Things you may never think of such as portland cement (no not from Portland, Oregon) which is used to make concrete. Other things include sand and gravel, sulfur, salt, and many more. Go to the map of the United States, use the mouse to point on any state and see which minerals are mined. Have fun!
