Uranium 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 longterm problem may result from naturally induced leaching, if the ore contains the mineral pyrite (FeS 2 ), as with the uranium deposits in Thuringia, Germany, for example).

Heap Leach and Ion-Exchange Facilities NRC.gov

Heap leach/ion-exchange operations involve the following process: Small pieces of uncrushed ore are placed in a "heap" on an impervious pad of plastic, clay, or asphalt, with perforated pipes under the heap. An acidic solution is then sprayed over the ore to dissolve the uranium it contains.

Uranium Heap Leaching nuclear-power.net

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 their division from other earth materials. In 2012, the percentage of the mined uranium produced by heap leaching

Heap leaching Wikipedia

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from oreusing a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ore, whereas in situ mining lacks these liners and pulls pregnant solution up to obtain the minerals. Heap leaching is widely used i

Acid leaching of agglomerated ore stacked to 5m occurs in four 2m x 2m x 6m leach cribs. In addition to the cribs, eight 5m high columns (as shown below) with an internal diameter of 0.185m enable parallel leaching. This arrangement
