I am working in a company recycling lead-acid batteries. I have some lead dioxide from the positive plates and wish to extract the lead from it. What I have thought of so far is to decompose it in my furnace for it to become lead oxide then throw in coke to further reduce it to lead. The problem it that I do not know the temperature it decomposes and how long to heat it at that temperature. Also I would like to know if there is any danger in heating lead dioxide as I have read from its MSDS that it produces toxic fumes upon decomposition. As far as I know it only releases oxygen to form lead oxide. Please help as this is quite important. Thanks in advance!

Fumes will most likely contain just lead (either free or in form of some volatile compound), so their toxicity will be that of lead compounds.
