From my point of view, the biggest issue with economically recovering gold from gold-filled is the sheer amount of base metals relative to values.

What you should really be looking for is the proper way of recovering and refining your scrap jewelry into as pure a gold as you desire. I would advise you look into the ways of either dissolving the gold plating from the base metal in the jewelry, or dissolving the base metal from the jewelry while keeping the gold plating intact.
