Leaching process (solid-liquid extraction) | PPT
Leaching involves extracting a substance from a solid material by contact with a liquid. A simple example given is making green tea, where steeping a green tea bag in hot water extracts the green flavor from the solid bag into the liquid water. The principle of leaching is that it can be done in batches, semi-batches, or continuously at an ...

Answered: TRUE or FALSE. Leaching calculations… | bartleby
Leaching calculations are almost always based on the principle that the solid will not dissolve into the solvent. Thus, the concentrations x of solute in the solvent entrained in the slurry and y of the solute in the solvent liquid phase can be expressed on a solid-free basis without significantly changing the calculation.
