used. One of these methods is fractional distillation, which relies not on the boiling point, but upon relative density of the resulting vapors. When several components in a mixture have differing boiling points, the one with the lowest boiling point will have a lighter vapor than the second, which will have a lighter vapor than the third, and ...

Fractionating column - Wikipedia

A fractionating column is an essential item used in distillation of liquid mixtures so as to separate the mixture into its component parts, or fractions, based on the differences in volatilities. Fractionating columns are used in small scale laboratory distillations as well as for large scale industrial distillations.

Refining of Metals – Study Material for IIT JEE | askIITians

Some metals have very low melting point and soon vaporize on heating while the associated impurities remain the solid state. Zinc, mercury and arsenic are purified by this method. Vaccum distillation gives very pure product and is used in the refining of the metals of IA and IIA. By Fractional Distillation

Distillation - Wikipedia

Distillation is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation.Distillation may result in essentially complete separation (nearly pure components), or it may be a partial separation that increases …
