Mechanical Separation

To improve the purity of smashed battery components and materials, physical separation is the commonly used method. Physical separation is a method to separate the valuable components from spent LIBs by using the physical properties (e.g., colour, density, magnetism, particle size, and surface physical properties).

5.8: Resolution: Separation of Enantiomers

Separation of racemates into their component enantiomers is a process called resolution. Since enantiomers have identical physical properties, such as solubility and melting point, resolution is extremely difficult. Diastereomers, on the other hand, have different physical properties, and this fact is used to achieve resolution of racemates.
