Dissolve lead for extraction?

So, CRT tubes are heavily leaded glass on the sides and back, the face is barium and phosphor rich.

It's basically lead oxide added to typical glass.

What would be the best way to extract the lead with the ultimate goal being highly purified lead for use in battery plates?

Will Nitric Acid work If I grind up the glass into powder? What level of concentration and dilution would be appropriate? Can I heat the solution to precipitate the lead or do I need to neutralize it first? I would like to keep the lead free to culminate, but I will accept further processing to reach that point. The long term goal is to do this readily with materials and chemicals that can be obtained from natural sources. Thanks for your help.
