    Obtaining Zinc Oxide from Calamine Introduction Calamine is a mineral containing zinc carbonate (ZnCO₃) On heating it decomposes as: [IMAGE]ZnCO₃ ZnO + CO₂ (C = 12, 0 = 16, Zn = 65) This equation allows you to calculate a theoretical conversion of calamine into zinc oxide. As when using the theoretical conversion; [IMAGE]ZnCO₃ ZnO + CO₂ [IMAGE]65+12+48 65+16 + 12+32 [IMAGE]125 81 + 44 This means that one mole of calamine weighs 125g and when heated it produces
