Top 10 largest uranium mines in the world 2025

Uranium, a chemical element with a U symbol and an atomic mass equal to 238 u, has an atomic number 92. Highly reactive in energy-creating processes, uranium is far more common than silver and gold, and has proved to be far more practical than any ‘precious’ mineral in meeting the long-term needs of our planet’s human population. When uranium was discovered in 1789 by Martin Heinrich Klaproth, it’s likely the German chemist didn’t know how important the element would become to human life.

Used minimally in glazing and ceramics, uranium was originally mined as a byproduct of producing radium until the late 1930s. However, the discovery of nuclear fission, and the potential promise of nuclear power, changed everything. Most of the world’s largest uranium suppliers are based in countries with the largest uranium deposits. But having large reserves doesn’t necessarily translate to uranium production numbers.

Here are the top 10 largest uranium mines in the world.
