Galena For Sale Rocks, Minerals, and Fossils
Galena Galena (PbS) typically forms within hydrothermal veins in igneous and metamorphic rocks. Its silvery metallic luster, cubic crystals, and high density make Galena easy to identify. Minerals which contain enough metal to extract easily are called ore minerals, and Galena (lead sulfide) has been a primary ore of lead since ancient times.

Galena: PbS Galena is the primary ore mineral of lead. Worked for its lead content as early as 3000 BC, it is found in ore veins with sphalerite, pyrite, chalcopyrite, tennantitetetrahedrite, etc. and in skarns, as well as in sedimentary rocks where it may replace carbonate beds or be deposited in pore spaces.

Formation of Chloropyromorphite from Galena (PbS) in the ...
Galena, an insoluble lead sulfide mineral (PbS) frequently found in mining wastes, becomes unstable upon exposure to oxidizing conditions causing it to become a source of liable Pb forms in soils. Thus, a galena ore was reacted with synthetic hydroxyapatite [Ca 5 (PO 4 ) 3 OH] under various pH conditions to determine the formation rate of pyromorphite and the solubility of galena under the ambient condition.

Galena, Illinois Facts for Kids
The city is named for galena, the natural form of lead sulfide (PbS) and the most important lead ore. Native Americans mined the ore for use in burial rituals. The Havana Hopewell first traded galena in the area during the Middle Woodland period (c. 1–400 CE). However, the use of galena in the Havana territory is uncertain; very little has been identified in burial mounds.
