WebA process in which crystal formation is initiated by adding crystals of pure substance, is known as seeding. Fractional crystallisation It is based on the different solubilities of different compounds in a solvent. The compound having less solubility crystallises out first on cooling leaving behind others in solution. http://www.olabs.edu.in/?sub=73&brch=7&sim=110&cnt=1
