Leaching Process Leaching Environmental Assessment ...
Leaching is the process by which constituents of a solid material are released into a contacting water phase. Although some species may be more of an environmental concern than others, the leaching process is indiscriminant such that all constituents (e.g., major or minor matrix components as well as inorganic, organic and radionuclide contaminants) are released...

Leaching - chemeurope
In pedology, leaching is the loss of mineral and organic solutes due to percolation. It is a mechanism of soil formation. It is distinct from the soil forming process of eluviation, which is the loss of mineral and organic colloids. Leached and elluviated materials tend to be lost from top soil and deposited in subsoil.

Uranium processing - Leaching Britannica
Uranium processing - Uranium processing - Leaching: Roasted uranium ores are leached of their uranium values by both acidic and alkaline aqueous solutions. For the successful operation of all leaching systems, uranium must either be initially present in the more stable hexavalent state or be oxidized to that state in the leaching process. Acid leaching is commonly performed by agitating an

What is leaching? National Critical Zone Observatory
01-07-2016 Leaching is not to be confused with the use of leeches as medicine. The word “leaching” is believed to have been derived from either late Middle English “leche” or Old English “leccan” meaning to moisten and to allow leaking. Currently, leaching primarily describes the process of water carrying soluble substances or small particles through soil or rock.
