Does Flotation Separates Mixtures Based on Density?

The density of a liquid determines whether it will float on or sink in another liquid. A liquid will float if it is less dense than the liquid it is placed in. A liquid will sink if it is more dense than the liquid it is placed in.

What separates based on density?

A centrifuge can be utilized to separate two liquids that do not separate from each other as easily. The spinning action causes the denser liquid to collect on the bottom of the tube, thus displacing the less dense liquid to sit on top of it.

How is flotation used to separate mixtures?

Flotation is a process in Liquid-Solid Separation technology whereby solids in suspension are recovered by their attachment to gas (usually air) bubbles, usually with objective of removing the solids from the liquid. The particles most effectively removed are in the size range from 10 to 200 μm.
