Separation of a mixture of particles into its individual components
However, the separation is attained based only on the difference of densities. Furthermore, it seems not suitable for the separation and analysis of biological materials. So far, the principle of the magneto-Archimedes separation was provided and then, some demonstrations were carried out using relatively large particles of millimeters in size.
Methods of Separation of Mixtures with Examples
Gravity Separation. We use this process for the separation of a mixture having components of different densities. The powdered mixture undergoes with a stream of running water. The lighter components wash away with water, leaving the heavier ones. For example, a separation of gold particles from rocky substances occurs by gravity separation.

1.16: Methods for Separating Mixtures
Distillation is a purification process where the components of a liquid mixture are vaporized and then condensed and isolated. In simple distillation, a mixture is heated, and the most volatile component vaporizes at the lowest temperature. The vapor passes through a cooled tube (a condenser), where it condenses back into its liquid state.
