Can anyone explain this?

Same as centrifugal decanter used in low density same for in extraction.

As additional work needs to be done to separate as the density difference is low.

The density difference is very small so that having same melting point so that it difficult to separation.

Also we can use evaporator to separate the liquid based on density difference.
