Lead Statistics and Information

Lead is a very corrosion-resistant dense ductile and malleable blue-gray metal that has been used for at least 5 000 years Early uses of lead included building materials pigments for glazing ceramics and pipes for transporting water The castles and cathedrals of Europe contain considerable quantities of lead in decorative fixtures roofs pipes and windows

3 Technologies in Exploration Mining and Processing

In addition the process of mining commonly exposes ore to more rapid oxidation by meteoric water which naturally affects the environment Therefore understanding the movement of fluids through the Earth for example through enhanced hydrologic models will be critical for future mineral exploration as well as for effectively closing mines that have completed their life cycle (NRC 1996b)

Lead Mining Techniques

Lead is extracted from ores dug from under-ground mines Lead is also found in conjunction with other metals such as silver and zinc Lead materials are mined as a by- product of these other more valuable metals Extracting the lead materials from the ore is a tedious process First the lead ore is ground into small salt-like particles
