Separation of particles of various sizes, shapes and densities by allowing them to settle in a fluid is called__________________?
Correct answer: A. Classification
- A. Classification
- B. Froth floatation
- C. Thickening
- D. Clarification
Explanation
Classification separates suspended particles according to their settling behaviour, which depends mainly on size, shape, and density. Froth flotation instead uses differences in surface properties, while thickening and clarification describe liquid-solid separation objectives.
