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.
