Basics of Leaching Separation Technology Articles

Simply put leaching generally refers to the removal of a substance from a solid via a liquid extraction media 194 The desired component diffuses into the solvent from its natural solid form 194 Examples of leaching include the removal of sugar from sugar beets with hot water and the removal of nickel salts or gold from their natural solid beds with sulfuric acid solutions
