Give the way how to manufacture oxygen

Oxygen is primarily manufactured industrially through the fractional distillation of liquid air. Air is first purified to remove carbon dioxide and water vapor, then compressed and cooled to a very low temperature until it liquefies. This liquid air is then slowly warmed, allowing its components (nitrogen, argon, and oxygen) to boil off at their different boiling points and be collected separately.
