    OverviewLead ore depositsImportanceCrystal structureGeochemistryGalena usesSee alsoFurther reading

    Galena is the main ore of lead, used since ancient times. Because of its somewhat low melting point, it was easy to liberate by smelting. It typically forms in low-temperature sedimentary deposits. In some deposits the galena contains about 1–2% silver, a byproduct that far outweighs the main lead ore in revenue. In these deposits significant amounts of silver occur as included silver sulfide mineral phases or as limited silver in solid solutionwithin the galena structure. These argentiferous galenas have long b
