In ore processing, leaching results in uranium being present in which state?

• A. As a metallic solid
• B. As a gas
• C. As a crystalline oxide
• D. In an aqueous solution

Answer: (D)

Leaching uses a liquid solvent to dissolve soluble components of the ore, turning the solid ore into a solution. For uranium, that means it is released from the mineral and carried away as dissolved ions in the aqueous phase—an aqueous solution. It isn’t left as a solid metal, a gas, or a crystalline oxide at this stage. The uranium stays dissolved so the next steps can recover it from the liquid.
