A separation process is a method that converts a mixture or solution of chemical substances into two or more distinct product mixtures. Separations exploit differences in chemical properties or physical properties (such as size, shape, mass, density, or chemical affinity)

Separation Techniques | Classification of Matter

A separation process or technique is a method that converts a mixture or solution of chemical substances into two or more distinct product mixtures.At least one of results of the separation is enriched in one or more of the source mixture’s constituents. In some cases, a separation may fully divide the mixture into pure constituents.
