10. Separation of Neon Neon is obtained for commercial purposes from air by the process of fractional distillation. In this process, air is cooled until it liquefies, and then it is gradually allowed to warm. The tiny fraction of the air that boils off at -246.08°C is neon, which is then collected. Some minerals also contain tiny amounts of trapped neon gas. Neon is obtained for commercial purposes from air by the process of fractional distillation.
