Leaching – Notes Read

23/06/2020  Chemical Mining Leaching. Leaching is a process in which one or more solutes are extracted from a solid, using a liquid solvent. Both phases come into intimate contact and the solute or solutes can diffuse from the solid to the liquid phase, resulting in a separation of the original components of the solid. Examples. The sugaris leached from the beets with hot
