IT'S MINED
In its pure form, the mystery element is a silvery white metal. The majority of this element on Earth is found in the planet's core, or center. However, there are deposits closer to Earth's surface. The United States gets half its supply of this element from mines in Canada and Australia. It gets the other half through recycling programs that collected about 119,000 tons of the element in 2007.
