Tantalum Niobium- Metalcess

Lead oxide ore, mainly in the form of cerussite and anglesite, is originated from primary lead sulfide ore which gradually changed its property under efflorescence and carbonate salt environment. In a lead deposit, lead oxide and lead sulfide usually is detected at the upper layer and lower layer separately.
