Leaching is a mass transfer process which takes place through the extraction of a substance from a solid material that has come into contact with the liquid. Leaching is the normal mechanism by which water-soluble compounds from soil or waste are washed out. Such leached-out contaminants affect surface and subsurface water contamination.
The gold ore sample from metamorphosed Paleoproterozoic deposit of high-sulfidation epithermal type was obtained for leaching tests.
