how to extract lead from leaded glass CRT tubes...?

I've been reading for a while trying to find a safe way to extract and refine lead from CRT sources, for use in batteries. It is apparently not readily available knowledge.

I've read that it will leach into wine... is that because of acidity? Would vinegar also leach it out?

And if I were to use a liquid to pull it from the glass, how would I refine the lead from the liquid? Boil it?

Is there a safe temperature I can melt the glass to that will make it possible for the molten lead and molten glass to separate through centrifugal or vibrational force?

Can I heat the wine out to leave behind pure lead without vaporizing lead and causing health risks?

I really need to learn more about this potential because I have plenty of CRTs and could easily get more, and I would really like to build custom batteries for use in home energy management.

Any knowledge you could share, or direction to good sources for this information would be greatly appreciated and also, would come up on search results if someone else ever tried to find this answer like I did. You would be doing a great service.
