Leaching Process

 · The process of leaching generally concerns with processes where the solid is inert and contains soluble solute which is extracted from the inert solid with the help of chemical reaction; for example leaching of valuable metals from waste materials by using sulphuric acid. The process of leaching is extremely common in metallurgical industries.
