Limestone and chalk are both forms of calcium carbonate and dolomite is a mixture of calcium and magnesium carbonates. All have impurities such as clay but some rocks are over 97% pure. Limestone and other products derived from it are used extensively in the construction industry and to neutralise acidic compounds in a variety of contexts.
Calcination, the heating of solids to a high temperature for the purpose of removing volatile substances, oxidizing a portion of mass, or rendering them friable. Calcination, therefore, is sometimes considered a process of purification. A typical example is the manufacture of lime from limestone.
