There is no such thing as 24 bits CD. What can be called a 24 bits remaster is a new 16 bits CD mastered from a 24 bits tape.
All audio CDs are strictly 16 bits, even HDCD ones.
The process called dithering, explained
here, allows to increase the definition of low frequencies adding high frequency noise. CDs processed this way are sometimes said to have "20 bits quality", for example.
