Correct answer: B. Selectivity index
- A. Separation efficiency
- B. Selectivity index
- C. Concentration ratio
- D. None of these
Explanation
The selectivity index combines separation performance into one measure by taking the geometric mean of the relative recoveries and relative rejections of the two minerals. Separation efficiency is a different overall performance measure.
