• Extracting Lead Materials from Ore

    Usually, lead is found in conjunction with other metals such as silver and zinc. Lead materials are mined as a by product of these other more valuable metals. Extracting the lead materials from the ore is a multi-step process. First the lead ore is ground into small particles that are less than 0.1mm, giving the ore a texture similar to table salt.

    OverviewLead ore depositsImportanceCrystal structureGeochemistryGalena usesGalena, also called lead glance, is the natural mineral form of lead sulfide. It is the most important ore of lead and an important source of silver. Galena is one of the most abundant and widely distributed sulfide minerals. It crystallizes in the cubic crystal system often showing octahedral forms. It is often associated with the minerals sphalerite, calcite and fluorite.

  • Galena Wikipedia

    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
