Leaching

Leaching The removal of a soluble fraction in the form of a solution from an insoluble permeable solid with which it is associated The separation usually involves selective dissolving with or without diffusion but in the extreme case of simple washing it consists merely of the displacement with some mixing of one interstitial liquid by another with which it is miscible.
