Separation by crystallization

Web1 Nov 2014 · If the substances in a mixed solution have sufficiently different solubilities (this is defined as the maximum amount of solid that can be dissolved in a volume of solvent), they can be separated from the mixture by fractional crystallisation. This experiment, which you can try, demonstrates the principle of how the process works. Try it yourself WebCrystallization from solution is a separation technique where a solid phase is separated from a mother liquor. In contrast to other separation processes, however, the dispersed phase consisting of numerous solid particles also forms the final product, that has to meet the required product specifications. How does crystallization separation work?
