A process for separating O2 from air, that includes the steps effecting an increase in pressure of an air stream, magnetically concentrating O2 in one portion of the pressurized air stream, the one portion then being an oxygen rich stream, and there being another portion of the air stream being an oxygen lean stream, compressing the oxygen rich stream and removing water and carbon dioxide therefrom, to provide a resultant stream, and cryogenically separating said resultant stream into a concentrated oxygen stream and a waste stream.

I claim: 1. A process for separating O2 from air, that includes the steps a) effecting an increase in pressure of an air stream, b) magnetically concentrating O2 in one portion of the pressurized air stream, said one portion then being an oxygen rich stream, and there being another portion of the air stream being an oxygen lean stream, c) compressing the oxygen rich stream and removing water and carbon dioxide therefrom, to provide a resultant stream, d) and cryogenically separating said resultant stream into a concentrated oxygen stream and a waste stream. 2. The process of claim 1 wherein said step d) concentrated oxygen stream contains at least about 99% oxygen, and said waste stream contains less than about 5% oxygen. 3. The process of claim 1 wherein said step b) oxygen rich air stream has an oxygen content of about 30% and said oxygen lean air stream has an oxygen content of about 20%. 4. The process of claim 1 wherein said step a) employs a compressor operating at reduced work output as compensated for by operation of said magnetic concentrating of O2. 5. The process of claim 1 wherein said step a) increases the pressure of said air stream to about 0.01 bar. 6. The process of claim 1 including providing an and operating a superconducting magnetic separator to effect said step b) concentrating of O2 in said one portion of the pressurized air stream. 7. The process of claim 1 including providing and operating a first scoop to separate the magnetically concentrated O2 in said portion of the pressurized air stream. 8. The process of claim 7 including providing and operating a second scoop to separate and remove an oxygen lean stream. 9. The process of claim 8 including removing a waste stream from the streams separated by said scoops. 10. The method of claim 1 wherein said a) step includes operating a fan to increase said air stream pressure for magnetic concentration of O2. 11. The process of claim 1 wherein said step a) increases the pressure of said air stream to about 0.01 bar. 12. The process of claim 1 including one or more of the following processes receiving said oxygen rich air stream, i) oxygen input for process swing absorption ii) combustion air input for large power plants iii) oxygen input to a sewage treatment facility iv) oxygen input to a chemical process plant v) oxygen input to a bleaching operation in paper making vi) oxygen input to a metallurgical process. 13. The claim 1 process for separating O2 from air, that includes the steps: a) providing three stages of magnetic concentration and separation of O2 from air, and respectively producing rich, richer and richest O2 product streams, each stage also producing a waste stream containing air and O2, b) and recycling at least one of said waste streams produced by one or more of said stages back to the input side of a preceding stage. 14. A process for separating O2 from air, that includes the steps a) effecting an increase in pressure of an air stream, b) magnetically concentrating O2 in one portion of the pressurized air stream, said one portion then being an oxygen rich stream, and there being a second portion of the air stream being an oxygen lean stream, c) including employing a compressor operating at reduced work output as compensated for by operation of said magnetic concentrating of O2. 15. The process of claim 14 including providing and operating a first scoop for removing said oxygen rich stream, and providing and operating a second scoop for removing said oxygen lean stream. 16. The process of claim 15 wherein said scoops are configured for by-passing flow of a portion of the air stream as a waste stream. 17. The process of claim 16 wherein said scoops are spaced apart in the direction of a magnetic field produced for said magnetic concentrating, and including allowing passage of said third stream between said scoops.
