Study Notes
Leaching
- The controlling factor in the rate of extraction is the rate of diffusion of the solute from the solid to the solvent.
- Percolation is a method of leaching where the raw material forms a permeable bed through which the solvent percolates.
- An example of solid/liquid extraction is leaching, which involves the separation of a soluble substance from an insoluble solid.
- Leaching is a process of solid/liquid extraction, where a solute is extracted from a solid using a solvent.
- 'Miscella' and 'marc' are terms associated with the process of leaching.
- The term used for the exhausted solids in the process of leaching is 'marc'.
