Extracting Lead Materials from Ore

2021-11-24  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.. Only about half of the lead materials used today are produced from mining, the rest is obtained from ...
