Context & Assumptions

The equilibrium relationship in leaching determines the distribution of a solute between a solid matrix and a liquid solvent. By assuming ideal contact, engineers can predict the final concentration of the extract and the composition of the liquid retained in the residue. This calculation is fundamental for designing separation stages in industries such as hydrometallurgy and food processing.
