Sep 18, 2009·Answers. A physical separation is a separation (i.e. one solution becoming two or more solutions) based upon the physical properties of the solutions being separated. For example, if the two solutions are two oils with different specific volumes, a physical separation is letting those two oil settle and separate, with two streams (one from the top,

OverviewComplete and incomplete separationSeparating liquidsList of separation techniquesElectrophoresisA 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 between the constituents of a mixture. Processes are often classified according to the particular
