What Is Lead Smelting? (with picture) wisegeek

High grade ores such as galena had to be used to recover sufficient quantities of lead. The pure, molten lead flowed from the smelters, forming slabs of raw lead for later use. This process was used for thousands of years and was possible due to the relatively low temperatures needed for lead smelting.
