Cryogenic separation - Wikiversity

The main disadvantage is the cost of the liquid nitrogen system. Cryogenic grinding is widely used for the reduction in size of particles. A small particle size is desirable when mixing materials, as cooling to cryogenic temperatures makes the materials brittle and consequently easier to break into small particles.

Cryogenic processes can also use "dry ice" (i.e., solid CO 2) or compressed CO 2 to embrittle the feed material prior to grinding. However, like liquid nitrogen, a great amount of energy is required to compress the CO 2 gas into "dry ice". These additional costs tend to limit the use of cryogenic grinding to high value materials.
