Extracting Lead Materials from Ore. Lead is a dense, soft, low-melting metal. Lead is the densest common metal except for gold, and this quality makes it effective in sound barriers and as a shield against X-rays.Lead resists corrosion by water, so it makes a long-lasting roofing material..

Firstly the lead was smelted in a furnace to remove the lead from the ore. Then the lead was removed and heated in a shallow hearth. Powerful hand operated bellows were used to raise the temperature to about 1,100°c and, at the same time, cause the silver to separate from the lead. It was at this point the silver was dawn off and poured into
