Uranium is recovered from its ore (pitchblende) by________________?
Correct answer: B. Leaching with sulphuric acid
- A. Froth floatation technique
- B. Leaching with sulphuric acid
- C. Smelting in a furnace
- D. Dissolving in water
Explanation
Pitchblende is treated by leaching with sulphuric acid, which dissolves uranium compounds into solution for subsequent purification. Froth flotation concentrates ores but does not directly recover the uranium from the concentrate.
