What is Leaching? Definition from Corrosionpedia

Sep 04, 2018· Leaching is the preferential removal of one element from a solid solution, such as the loss of zinc from brass (dezincification). Leaching is also the process of extracting minerals from a solid by dissolving them in a liquid, either naturally or through an industrial process. Leaching causes reduction of mechanical strength and can result in structure failure.
