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 (leaching). 2. The separation of the solution from the remaining solid (washing). Factors influencing the rate of extraction: There are four important factors to be considered: 1. Particle .
