Historical Lime Production in Southeastern Arizona

The chemical reaction involved in turning limestone into lime is relatively simple. When limestone (CaCO2) is heated to between 812 and 1100 degrees Celsius (de-pending on the elevation and the purity of the limestone), carbon dioxide (CO2) is released leaving only lime (CaO) and any impurities that may have been in the limestone (Wingate 1985).
