Galena ore.

Galena is by far the greatest ore of lead. Galena is the most common mineral containing lead, and contains mostly lead. Since the extraction process is so simple, lead has been extracted from Galena since the earliest times. To quote Allen N Wollscheidt, "Galena, back 75 years ago, was the stuff -- the crystal -- of crystal radio sets. The elemental analysis by XRF showed that the galena ore is composed mainly of PbS with metals such as Sn, Fe and Zn occurring as minor elements and Mn, Rb, Sr and Nb as traces. The XRD analysis indicated galena as the dominant mineral phase, with the presence of associated minerals, such as α-quartz (SiO 2 ), sphalerite (ZnS), cassiterite ...Do not melt the silver.

A 581-acre (235 ha) section of the city is listed on the National Register of Historic Places as the Galena Historic District.The city is named for the mineral galena, which was in the ore that formed the basis for the region's early lead mining economy.

RAW GALENA 1" Mineral Specimen . Galena grows in beautiful metallic cubes. Often refined as lead ore, galena can also be used to teach students about a mineral's luster, streak, and cleavage. Because of the lead in the chemical formula, it is much denser than other minerals, which makes it seem unnaturally heavy for its size.

Galena Galena is the major ore of lead, and has been mined and worked since ancient times, e.g. the Romans used lead for weights, coins, vases, plumbing. Galena, a sulphide mineral, contains up to 86% lead, and may contain up to 1% silver. The large volume of galena that is processed for lead produces enough silver as a by-product to also make galena the leading ore of silver.

Pyrite Pyrite, often known as fool’s gold, can be one of the most dangerous minerals. Galena Facts. Galena” is Latin for lead sulfide. In the peak year of 1845, the mining district, with Galena as its hub, produced almost 85% of the nation’s lead. The “Lead Rush” preceded the California “Gold Rush” by 20 years. Galena claimed 9 residents who reached the rank of General for service rendered during the Civil War.

The principal sulfides are pyrite, sphalerite, and galena, accompanied by lesser amounts of chalcopyrite, arsenopyrite and tetrahedrite. Cu-pyrite ore bodies consist mainly of pyrite, arsenopyrite, chalcopyrite plus minor sphalerite, galena and sulfosalts. Fluorite, barite, quartz and carbonate are the gangue minerals.
