How is oxygen mined or produced?

Answer 1

Oxygen is already present in the earths atmosphere. Its presence is 21% in the entire composition of the atmospheric gases which comprises of many other gases and rare gases.

The simplest way to generate oxygen is by the process of electrolysis of water. It is process in which controlled direct current (DC) is passed through the water through metal electrodes. The water is composed of one part of oxygen and 2 parts of hydrogen. By process of electrolysis the oxygen and hydrogen molecules are separated and released at the electrodes. Two molecules of hydrogen are released at the negative electrode and one molecule of oxygen at the the positive electrode. This can be collected by making appropriate arrangements to collect the gas.

There are many other methods of generating oxygen, but electrolysis is the simplest one.

Answer 2

Oxygen is typically produced through air separation methods, where air is compressed, cooled, and then distilled to separate oxygen from other components like nitrogen and argon. This process can be achieved using cryogenic distillation or other techniques such as pressure swing adsorption or membrane separation. Oxygen can also be produced through the electrolysis of water, where an electric current is passed through water to split it into hydrogen and oxygen gas.

Answer 3

Oxygen is produced when plants make their food using photosynthesis. The other way to get oxygen is the separation of air using either a cryogenic distillation process.

Answer 4

The oxygen in air is produced by photosynthesis.
