Uranium Heap Leaching nuclear-power

Heap leaching is an extraction process from ore which has been mined and placed in piles on the surface. Heap leaching is based on the use of a series of chemical reactions that absorb specific minerals and re-separate them after

Uranium Heap Leaching

After completion of the leaching process (within months to years), the leached ore is either left in place, or removed to a disposal site, and new ore is placed on the leach pad (so-called on/off scheme, or dynamic heap leaching). During leaching, the piles present a hazard because of release of dust, radon gas and leaching liquid. After completion of the leaching process, a
