A separation process is a method for separating two or more separate product mixtures from a mixture or solution of chemical ingredients. One or more constituents of the source mixture are enriched in at least one of the separation's result mixtures. In some situations, separating the mixture into pure ingredients is possible. Separations take advantage of variations in a mixture's constituents' chemical or physical qualities (such as size, shape, mass, density, or chemical affinity). Processes are frequently categorised based on the specific differences they employ to accomplish separation. If no single difference can be used to create the desired separation, many processes can typically be combined to do so. Distillation, extraction, zone refining, and other techniques are used in the separation process. The adsorption of atoms, ions, or molecules from a gas or liquid to a surface is known as adsorption. Distillation is a method for separating liquids with different boiling points. Chromatography is a technique for separating dissolved particles based on their interactions.
