Specimen and photo by Arkenstone / www.iRocks.com. What is Galena? Galena is a lead sulfide mineral with a chemical composition of PbS. It is the world's primary ore of lead and is mined from a large number of deposits in many countries. It is found in igneous and metamorphic rocks in medium- to low-temperature hydrothermal veins. Other uses of galena: While galena is primarily important as lead ore, there are a few uses for this mineral in its unrefined form. Crystals of galena are used as detectors, to convert radio signals to sound, in simple, early radios called crystal sets. Since ancient times, galena has been ground to produce Kohl, which is used as eye make-up.Galena, a gray lead sulfide (PbS), the chief ore mineral of lead. One of the most widely distributed sulfide minerals, it occurs in many different types of deposits, often in metalliferous veins, as at Broken Hill, Australia; Coeur d’Alene, Idaho, U.S.; Clausthal Zellerfeld, Ger.; and Cornwall,
Some economic chalcopyrite deposits form as hydrothermal fluids dissolve copper from igneous rocks and then precipitate it in surrounding contact-metamorphosed sedimentary rocks.
