Cerussite (PbCO3): Cerussite is a lead carbonate mineral that forms in the oxidized zone of lead ore deposits. It is typically found as prismatic crystals or granular masses and can be colorless, white, or gray in color. Cerussite is less common than galena but can be an important secondary lead mineral in some deposits.
