Oksigén mangrupikeun salah sahiji komponén hawa sareng teu warnaan sareng bau. Oksigén éta mumbul tibatan hawa. Cara pikeun ngahasilkeun oksigén dina skala ageung nyaéta pikeun hawa cair. Mimiti, hawa dikomprés, diambahkeun teras beku kana hawa cair. Ti saprak gas mulut sareng nitrogén parantos langkung handap titik ngagolakkeun tibatan oksigén, naon anu sésana saatos frenchation oksigat cair, anu tiasa disimpen dina botol tekanan tinggi. All oxidation reactions and combustion processes require oxygen. For example, in the steelmaking process, impurities such as sulfur and phosphorus are removed. The temperature of the mixture of oxygen and acetylene is as high as 3500 °C, which is used for welding and cutting of steel. Oxygen is required for glass making, cement production, mineral roasting and hydrocarbon processing. Liquid oxygen is also used as rocket fuel and is cheaper than other fuels. People who work in hypoxic or oxygen-deficient environments, such as divers and astronauts, are vital to sustaining life. Nanging, kaayaan aktivitas aktif, sapertos Ho sareng H2O2, karusakan kana kulit sareng panon disababkeun ku sinar ultraviolet aranjeunna hubunganana sareng jaringan biologis.
Most commercial oxygen is made from air separation, where the air is liquefied and purified by distillation. Low temperature total distillation can also be used.

Other purification methods include pressure swing adsorption and membrane separation.
