Jason is correct you need to determine if it is epoxy or Portland based terrazzo. If you see cracking in the terrazzo chances are it is Portland based. Denisfiers can not be used on epoxy..For Portland terrazzo use standard marble pads. for epoxy use one designed for Engineered stone such as the Ceramica EX by Alpha
We do a lot of the old terrazzo in Florida. We treat it just like marble floors. I will usually polish with a marble polishing compound after a 400 resin. I start with whatever the stone dictates as far as scratching is concerned or glues on surface from carpet, ect. This picture was one we did last week in Marco Island Florida.
Hope this helps

Its good to know if the binder is concrete or epoxy. Use harder resins for terrazzo. I usually start at 220 metal or 50 resin if it's in decent shape. If it's concrete, you can densify after 400, and work your way up, or you can use a powder polish and get a nice shine as well at 800 or above. Sometimes it's good to use a concrete densifyer/coating as a topical.

I haven't done much terrazzo estimates as I don't see very much of it where I am. I have a steakhouse that has a matt finish terrazzo (most of it is dark with light accent pieces on the borders). Approx. 2500 sq ft. I took my razor and didn't find a topical. The owner wants the light scratches removed and wants the finish to have a high gloss. Nice place with a black baby grand piano in a fun area just a few blocks from downtown. From what I know, there are special pads for terrazzo, is that right. The building was built in 1999. I do not know the age of the floor.
I was thinking of a deep clean, diamond hone process then crystallizer. Does anybody else have anything they can add to help me with estimating the project?
