Lead Materials Ore Extraction Lead Shielding, Lead

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

LEAD ZINC EXTRACTION PROCESSES EPrints

The most important lead ore is galena (lead sulfide). Other important ores such as cerrusite (lead carbonate) and anglesite (lead sulfate) may be regarded as weathered products of galena and they are usually found nearer to the surface. Lead and zinc ores often occur together and for most extraction methods they have to be separated.
