A:

Centrifugation

 

PRINCIPLE: This method is based on the principle of settling down under a mechanical rotation where the insoluble heavier solid particles present in an insoluble solid-liquid mixture.

TECHNIQUE: The mixture is placed in a test-tube and kept in a centrifugation machine. On centrifugation, the solid particles settle down under the influence of an outward centrifugal force and the liquid floats above it.
