Crystallization is also a chemical solidâliquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs. In chemical engineering crystallization occurs in a crystallizer.
Recrystallization is the most common and is defined as the metamorphic process by which crystals are packed together creating a new crystal structure. Recrystallization requires a lot of heat and pressure, and the process changes the mineral's size and shape, yet the basic composition remains unchanged.
