Volatile component can be separated from non-volatile component by the process of
sublimation
The volatile component can be separated from the non-volatile component by the process of sublimation. We can separate two solids if one of them can sublime faster than the other or even when one cannot sublime at all.
Sublimation is defined as the transition of a substance from the solid state directly to the gaseous state without undergoing through the intermediate liquid state. For example, camphor.
