Wyoming's Uranium Drama: Risks, Rewards and Remorse

Nov 08, 2014· Processed ore is often transported as a partially refined powder called yellowcake—a uranium oxide, U 3 O 8. Uranium produced in Wyoming has already provided the energy equivalent to that of 5.9 billion barrels of fuel oil or 1.9 billion tons of coal. For comparison, Wyoming coal production in the early 2000s peaked at close to 450 million
