When to use bei and mit in German? - was ist base bei navyfield

Has anyone a list of when to use these two words? I learned that (MIT) = (a) in such cases, I want a Coke (MIT) ice. So, I've gone (MIT), my friend.

I learned that (at) = (or close relatives), my apartment is'm at the park, too, (at) = (someone in the house) I (EIB) Mary. Additionally, (at) = (a) Base Welcome to ... and finally (at) = (a work for a company) I work at Base.
What am I missing?
