galena structure

  • Galena

    Galena is a noticeably dense mineral, having a density of about 7.6 gm/cm3. It has a metallic luster. Galena has the same cubic structure as common table salt, NaCl. The samples pictured here are on display at the Smithsonian Museum of Natural History.

    Lead ore is most commonly found as lead sulphide (PbS), galena, a heavy, shiny grey metallic ore with a conspicuous cubic cleavage, but locally pyromorphite, lead chlorophosphate (Pb5(PO4)3Cl), was worked on Green Hill, near Charterhouse and on Blagdon Hill. Around Charterhouse, the lead ore contained small

    Samples of galena feel significantly heavier than similarsized samples of most minerals, including other metallic minerals. The crystal structures of galena (PbS) and halite (salt or NaCl) are identical, so it is not surprising that the two exhibit similar perfect cubic cleavage. Both minerals will break along three directions of

  • Galena Mineral Uses and Properties Geology

    Structure of galena: Galena has a chemical composition of PbS. That means it contains an equal number of lead and sulfide ions. The ions are arranged in a cubic pattern that repeats in all directions. This structure is what causes crystals of galena to have a cubic habit and causes galena to break in three directions at right
