Gold Smelting & Refining Process
There is an alternative process that employs fluxes, carbon and lead oxide (litharge). In this case carbon helps to reduce oxides and distribute the temperature correctly in the crucible. Flour is the most known source of carbon. When the charge is taken high temperatures lead oxide is reduced and metallic lead is produced.

Lead-Acid Batteries and Steps of Battery Manufacturing Process
Lead oxide is obtained by masses of lead from melting furnaces either by Milling or Barton Pot process methods. In the milling process, the tumbling action generated by the rotating mill on solid lead generates heat and then the surface of the lead gets oxidized. The surface layers of the oxide are removed while the lead particles roll in the drum.

Lead smelting - Wikipedia
Galena, the most common mineral of lead, is primarily lead sulfide (PbS).The sulfide is oxidized to a sulfite (PbSO 3) which thermally decomposes into lead oxide and sulfur dioxide gas.(PbO and SO 2) The sulfur dioxide (like the carbon dioxide in the example above) is expelled, and the lead oxide is reduced. Anglesite, Cerussite, Pyromorphite, Mimetite and Wulfenite are other lead ores.
