Continuous agitation leaching usually applies the concurrent leaching procedure, and if it applies the countercurrent or crossflow leaching, solid-liquid separation operations should be added between all stages. Agitation leaching of intermittent operation is generally concurrent leaching, but it can apply crossflow and concurrent …
Leaching Process
The Leaching process is a universal process – Water will leach the components of any material it comes in contact with, from its surface or the interior of the material (based on the porous nature of the material). Using this process, the ore of metal can be concentrated by causing a chemical reaction with a reagent which would lead to the ...

Leaching
Agitation leaching: Agitation leaching is a process where the soil is slurried with the extraction fluid for a period of time. When equilibrium between the metal on the soils surface and the metal contained by the solution is approached, the solubilization of the metal in the soil is slowed, and the extraction is considered to be complete. At ...
