    Secondary minerals are formed in the upper parts of the vein and are derived from oxidation of the original (primary) lead ore (galena) due to surface waters entering the vein Cerussite (white lead ore, lead carbonate, PbCO3) is the only secondary lead mineral to have been worked In the 1820s, James Braid, surgeon to the mines recognised that cerussite formed from03/04/2020· Galena, or lead sulfide, the world's major source of lead ore, occurs worldwide; and, it is mined in many countries, including the United States, Australia and China Lead ore comes from underground mining operations, where the lead ore seams are blasted out of the ground and transported to the surface for refinement Lead is commonly found in deposits with otherHow Is Lead Mined?
