Leaching - an overview | ScienceDirect Topics

Jul 01, 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.
