Lead - CAMEO

Native metallic lead was found and used from about 3600-2600 BCE when the technique for obtaining lead from roasting the sulfide ore (galena) was discovered. Lead was used to make small cast items such as coins and statuettes as well as larger items such as plumbing pipes, spires, statues, cisterns, and gargoyles.

It accommodated a double-track railway system over some of its length that fed directly to an ore-dressing mill. The mill housed an ore separation technique, known as oil-flotation, a method that was in its infancy in 1912. Its advantage was that the metallic ore could be extracted profitably from relatively poor grade vein material.

Use and abuse of Pb-isotope fingerprinting technique and ...

Among these techniques, using lead IRA has certain advantages, as each geological source of lead can possess an independent isotopic ratio depending on its age (or time since the ore was formed) (Manton 1973, 1977; Rabinowitz 1987, 1995). There are four stable isotopes of lead: 204 Pb, 206 Pb, 207 Pb and 208 Pb.

Uranium–Lead Dating | SpringerLink

Uranium–Lead dating is the geological age-determination method that uses the radioactive decay of uranium (U) isotopes (238 U, 235 U, and also in this entry 232 Th) into stable isotopes of lead (Pb) (206 Pb, 207 Pb, and 208 Pb, respectively). U–Pb geochronology is the science of both the methodology but also the application of these methods to geological problems.

Lead Isotope - an overview | ScienceDirect Topics

Lead Isotope Ratio Analysis. The ratios of the four lead isotopes (Pb204, Pb 206, Pb 207, and Pb 208) in a lead ore specimen will depend upon the geological age of deposition of the ore. Thus, the lead isotope ratios are used to source the deposit used to produce archaeological objects containing lead.

Identification and Description of Mineral Processing ...

Lead is mined (extracted) almost exclusively in underground operations, though a few surface operations do exist. The use of underground or surface mining techniques depends on the proximity of the ore body to the surface, and the individual characteristics of each ore body determine the exact mining method. (U.S. EPA, 1993b, p. 14)

3 The principal lead ore, galena, is properly known as lead sulfide, and sulfur makes up a substantial portion of the mineral. The flotation process collects the sulfur-bearing portions of the ore, which also contains the valuable metal. First, the finely crushed ore is diluted with water and then poured into a tank called a flotation cell.
