Galena is the primary ore mineral of Lead. Worked for its lead content as early as 3000BC, it is found in ore veins with Sphalerite, Pyrite and/or Chalcopyrite, and in Sedimentary rocks as beds or impregmentations. The crystals are bright when fresh but often receive a dull tarnish after exposure to air. Galena is a common and popular mineral ...

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.

For example, the combination of lead and sulfur forms a sulfide mineral called galena. Many of the sulfide minerals are valuable ores, such as galena and sphalerite, the sulfide minerals that produce lead and zinc ore. In Kansas, many of the sulfide minerals are found in the southeastern corner of the state. Galena (hardness 2 1/2) Galena, the ...
