<P> A separation process 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 . Separations exploit differences in chemical properties or physical properties (such as size, shape, mass, density, or chemical affinity) between the constituents of a mixture . </P> <P> Processes are often classified according to the particular differences they use to achieve separation . If no single difference can be used to accomplish a desired separation, multiple operations can often be combined to achieve the desired end . </P>
