An archive is mealy a collection of object files.  When linked to 
program code with ld, the resulting elf contains a combination of all 
sections and object code etc. (See ar and ld documentation)

I do not know of a easy way to recover a collection of object files 
which you could then link to from another program.  You could try 
disassembling and writing new code if the library is not very complex or 
find an equivalent library to use.
