The process is exactly like you do your nug runs. The return will be small and runny/pliable. You can mix it with EJ Mix for great juice results (consistency wise). The effect is a heavy body high, great before bed time. However, the taste has something left to be desired. Not worth it IMHO based on the effort to achieve the return.
The best and easiest way to recycle ABV is to boil it in coconut oil and strain. The oil is great as an edible, and quite amazing as a topical by making a salve.
