The study on washability of coal is done by using the _____________ technique?
Correct answer: C. Heavy media separation
- A. Tabling
- B. Elutriation
- C. Heavy media separation
- D. None of these
Explanation
Coal washability is determined by float-sink testing in liquids of controlled density, commonly represented by heavy-media separation. Tabling and elutriation are concentration methods but do not provide the standard washability curve.
