Galena Facts – Galena History Museum

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.

Wisconsin Geological Natural History Survey » Galena

Galena - Wikipedia

Galena is the main ore of lead, used since ancient times.Because of its somewhat low melting point, it was easy to liberate by smelting.It typically forms in low-temperature sedimentary deposits. In some deposits the galena contains about 1–2% silver, a byproduct that far outweighs the main lead ore in revenue.In these deposits significant amounts of silver occur as included

Galena Group. 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, tennantite-tetrahedrite, etc. and in skarns, as well as in sedimentary rocks where it may replace carbonate beds or be deposited in pore spaces.

Lead processing Britannica

Galena often contains silver, zinc, copper, cadmium, bismuth, arsenic, and antimony; in fact, the value of the silver content often exceeds that of the lead, in which case it is deemed a silver ore. Other commercially significant lead-containing minerals are cerussite (lead carbonate) and anglesite (lead sulfate).

Lead - Wikipedia

The main lead-bearing mineral is galena (PbS), which is mostly found with zinc ores. Most other lead minerals are related to galena in some way; boulangerite, Pb 5 Sb 4 S 11, is a mixed sulfide derived from galena; anglesite, PbSO 4, is a product of galena oxidation; and cerussite or white lead ore, PbCO 3, is a decomposition product of galena.
