Stages of Hydrometallurgical Processes

Agitation leaching : 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 [10] 11 Process Stages...
