Lead Blast Furnace Extraction

The molten lead produced from the blast furnace is about 95-99% pure and is known as base bullion because of the purity attained. Again,it must be further refined to remove impurities since commercial lead must be about 99-99.999% pure. This base bullion is kept at a

The air blown into the bottom of the furnace is heated using the hot waste gases from the top. Heat energy is valuable, and it is important not to waste any. The coke (essentially impure carbon) burns in the blast of hot air to form carbon dioxide - a strongly exothermic reaction. This reaction is the main source of heat in the furnace.
