How do the companies on earth farm/get neon gas?

I have tried to research it but all I found conflicting answers so I was wondering if anyone has a concise explanation of the process of gathering it?

Compress air, cool it down, compress more, cool more, eventually you can get the gas down to a temperature where it condenses into a liquid.  Different gases condense at different temperatures, so you can actually get them separated by being careful about the temperature at which you siphon off liquid.  It's also how they get liquid nitrogen, helium, oxygen for medical use, CO2 for soda fountains at restaurants, and so on.
