Leaching (chemistry) - Wikipedia

Leaching is the process of a solute becoming detached or extracted from its carrier substance by way of a solvent. [1] Leaching is a naturally occurring process which scientists have adapted for a variety of applications with a variety of methods. Chapter (10) Solid-Liquid Extraction ((Leaching ))Leaching: is the separation of a solute from solid mixture by dissolving it in a liquid phase. Leaching occurs in two steps: 1. Contacting solvent and solid to effect a transfer of a solute
