In case of constant underflow extraction operation, the _______________________ at all solute concentration?
Correct answer: C. Both A. & B.
- A. Solids are drained to the same extent
- B. Ratio of the insoluble to solution is constant
- C. Both A. & B.
- D. Neither A. nor B.
Explanation
Constant underflow means that the amount of solution retained with the insoluble solids remains constant per unit mass of solids. Thus the ratio of insoluble solids to retained solution is constant, and the solids are drained to the same extent.
