Galena is the principal lead ore mineral. It is lead sulfide (PbS). When pure, it contains 86.6% lead and 13.4% sulfur. Galena is metallic lead gray with a bright metallic luster when freshly broken, and dark gray to black when weathered. It is brittle and very heavy (about 7.6 times as heavy as water).

Galena was founded in 1763 under the name Down's Cross Roads, after William Downs, a local tavern owner. The name was later changed to Georgetown Cross Roads sometime before 1813, and finally to Galena in 1858.

In the early 1860s, the town of Galena was built from the pine trees and stones from the surrounding mountainside. The town had all the familiar bustle of a pioneer village: homes, stores, hotels, stables, a school, a jail, and court of law. There were several churches, 7 saloons, and 11 sawmills powered by the area's creeks.

Galena is the most important ore of lead. Silver is often produced as a by-product. Most lead is consumed in making batteries, however, significant amounts are also used to make lead sheets, pipe and shot. It is also used to make low-melting-point alloys. Its use as a pigment has declined as has its use in making solder.

These fluids, in turn, reacted with preexisting galena and functioned as a silver trap. Lead sulfides with ε 109 Ag of ~0 and unusually rich in Ag, Sb, Bi, and As were the most probable sources of ancient silver, whereas samples with ε 109 Ag departing significantly from ~0 reflect low-temperature isotopic fractionation processes in the upper ...

Galena has been produced from the Upper Mississippi Valley zinc-lead district in Wisconsin since the seventeenth century. Some mines started by Native Americans may predate this. Major lead mining occurred from the 1800's until the late 1970's. A few small lead mines operated by individuals persist to the present day.

Galena (PbS) is lead sulfide, the principal ore of lead. It is steel gray, heavy (specific gravity is 7.4 to 7.6), and opaque and has a bright metallic silver-colored luster, although the shiny surface may be dulled by a coating of lead carbonate.
