Missouri Lead Mining History by County DNR
Ore minerals were galena (lead sulfide), cerussite (lead carbonate), sphalerite (zinc sulfide), smithsonite (zinc carbonate), barite (barium sulfate) and hemimorphite (zinc silicate). Chalcopyrite (copper iron sulfide) and malachite (copper carbonate) are present but not in mineable quantities.Get Price
