The smelting process is essentially very simple. Pellets of Galena are heated until they reach melting point. Because lead has a low melting point any impurities are not melted and are left as waste. The molten lead can be allowed to drain from the fire hearth into a collecting pot and then poured into moulds to form blocks of pure lead metal.

but a piece of ore was found and the galena separated from it had a silver content of 3 oz. 5 dwt. per ton of lead. Another piece of lead found on the site yielded 9 oz. i6 dwt. per ton; thus showing the order of variation that occurs in any lead ore deposit. In order to get some idea of a primitive lead smelting furnace we have to go to a ...
