Lead Ore / Lead Concentrate Smelting, Manufacturing

Lead Ore Smelting. Any of several minerals from which Lead is extracted. The primary ore is galena or Lead sulphite PbS. This is unstable, and on prolonged exposure to the atmosphere it oxidizes into the minerals cerussite PbCO3 and anglesite PbSO4.

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
