Lead associated with larger soil particles is generally less bioavailable than when attached to small particles, and encapsulation of Pb mineral phases with clays or quartz, for example, can also reduce Pb bioavailability (Chaney et al. 1989; Davis et al. 1993; Wixson and Davies 1993; Ruby et al. 1999).
Lead oxide particles emitted from car exhausts would be expected to dissolve in soil with adsorption of Pb on to Fe hydrous oxides and humus; other studies have shown that petrol- derived Pb has a strong affinity for Fe oxides in Roadside soils.
Abstract. An old lead mine tailings pile in Southeast Missouri is being used as a sanitary landfill. The tailings were found to consist of 60–70% dolomite, 20–30% mascovite/illite and trace amounts of quartz, galena, and calcite.

Lead is a naturally occurring metallic element usually associated with other ore minerals (primarily those of zinc, silver and copper) such as pyrite, sphalerite, quartz and barite.Trace amounts of other elements including gold are sometimes found with lead ore. The most common ore mineral of lead mined in the United States is galena with the chemical symbol PbS.

Lead is particularly strongly bound to humic matter in organic-rich soil and to iron oxides in mineral soil, and is rather immobile in the soil unless present at very high concentrations.

The high grade of the more massive galena ore often overloads the flotation system, and, with the decline of lead prices, it is not economical to recover the last percent or more of the lead mined.
In 1967, Missouri named galena, the natural mineral form of lead sulfide, as the state mineral in order to recognize the importance of lead mining in the region's. Lead ia Department of Mines, Minerals and Energy. Lead is a heavy, soft, ductile metal with a low melting point. Its chemical symbol is Pb.

Galena is a lead sulfide mineral with a chemical composition of PbS. It is the world's primary ore of lead and is mined from a large number of deposits in many countries. It is found in igneous and metamorphic rocks in medium- to low-temperature hydrothermal veins.

Did you know... Galena is the most abundant lead mineral, has been mined for millennia, and remains our major source of that metal. It is a metallic, lead-gray mineral with cubic cleavage and a distinctly high density that makes galena samples feel much ‘heavier’ than expected for their size.
The Old Lead Belt of southeastern Missouri was one of the leading producers of Pb ore for more than a century (1869–1972). Large quantities of contaminated mine waste have been, and continue to be, supplied to local streams.
Mine waste containing up to 20,000 mg/kg Pb primarily in the form of lead sulphide (PbS-galena) was present but no significant increase in BLL compared with a control population concluding that Pb as galena was not readily bioavailable 28 Danse, I. H., Garb, L. G. and Moore, R. H. 1995.
