Found naturally only in the form of its compds, never uncoined, in minerals such as limestone, dolomite, marble, chalk, iceland spar, gypsum, anhydrite, fluorite, apatite. Principal commercial source is limestone, q.v. Major commercial production by high temperature vacuum reduction of calcium oxide in aluminothermal process; less commonly by electrolysis followed by redistillation.

4. Some important reactions of Acids Acids are neutralised by reaction with metals, oxides, hydroxides or carbonates to form salts and other products. Apart from metals (which is an electron loss/gain redox reaction), the other reactants listed above are considered as bases, meaning they react by accepting a proton from an acid in forming the salt.
