Galena, also called lead glance, is the natural mineral form of lead (II) sulfide (PbS). It is the most important ore of lead and an important source of silver.
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.
Sep 4, 2023 · Galena, a mineral of both historical and geological significance, is a lead sulfide mineral with the chemical formula PbS. It stands out with its distinctive metallic luster and cubic crystal structure, often appearing as shiny, cubic or octahedral crystals.
Description and Identifying Characteristics. Its perfect cubic cleavage, metallic luster, lead-gray color, and relative softness readily distinguish galena from most other metallic minerals. Perhaps its most distinctive feature though, is its very high density (high specific gravity).
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, Eng. Large deposits also occur as replacements ...
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.
Galena is the most common mineral containing lead, and has been well-known throughout the centuries. It is often well crystallized and forms in many interesting and distinct crystal shapes.
Apr 1, 2019 · Galena is a very soft mineral, registering only 2.5 on the Moh's hardness scale. And even worse, galena has perfect cleavage and brittle tenacity. This means that specimens are very easily damaged by just a tiny chip or bruise. When dropped or smashed, galena easily splits into tiny cubes.
Galena is the primary ore mineral of lead. Its discovery dates back to 3000 BC, and its name is derived from the Latin word galena, meaning dross from melted lead. Properties of Galena. The key physical properties of Galena are as below: Cell Data. Space group: Fm3m. a = 5.936. Z = 4. Crystal Data. Cubic. Point group: 4/m 3 2/m.
May 8, 2018 · galena (gəlē´nə) or lead glance, lustrous, blue-gray mineral crystallizing usually in cubes, sometimes in octahedrons. It is the most important ore and the principal source of lead.
