Lead Mining Concentration process, flotation, filtering

MINING AND PROCESSING : Lead is known to naturally occur in free form in nature, but is generally obtained from the ores galena(PbS), anglesite (PbSO 4), cerussite (PbCO 3) and minum (Pb 3 O 4). It is never considered to be a rare element even though it makes up only about 0.0013% of the earth's crust since it is easily mined and refined.

Extracting Lead Materials from Ore

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

Secondary lead processing. Most of the lead produced comes from secondary sources. Lead scrap includes lead-acid batteries, cable coverings, pipes, sheets and lead coated, or terne bearing, metals. Solder, product waste and dross may also be recovered for its small lead content. Most secondary lead is used in batteries.
