The crude lead smelting video shows the full process of producing crude lead from lead ore. The ore and flux are first charged into a high-temperature furnace, where heat causes the metal to melt and impurities to separate as slag. The molten lead then settles at the bottom of the furnace, is tapped out, and transferred for further handling. Finally, the crude lead is cast into ingots or large blocks, clearly illustrating each step of the smelting operation. | Pansou Bae
