'mount' isn't the term, nor the action you need to do, with a Windows computer. You did not tell us what sort of computer or Operating System you are using. 'mount' is something common in the UNIX and UNIX-like world.
In the Windows world you just place a CD in the drive and it's there.
If that doesn't work for you, then ask another question, telling us what OS you have and what messages, or results, you are getting.
As for .BIN and .CUE formats:
.BIN is typically a binary format, that is seldom used in the Windows world. But .BIN is used in the UNIX-like and the Apple world. Are you sure whatever you have is for a Windows PC?
Some Windows programs may use .BIN, but they are rare. If the file you have is not for the Windows world, but you are trying to run it on a Windows PC, then that may not work.
.CUE can be one of several file types. I am going to guess that it is a CD image file, similar to the more common .ISO type. If that is true, then you may want to find a program to either burn the image to a usable CD format, OR (and this may be what you were inferring) there are programs that can take CD image files and (sort of) 'mount' them so that they appear as the CD they would be as if the CD image were actually burned.
As for what is in the .CUE (if it is a CD image) and what to do with that, that depends upon what it is to begin with.
