Calcium carbonate Essential Chemical Industry
They are limestone, chalk and dolomite. 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.
What is Quicklime? (with pictures)
Oct 18, 2019· To make it, limestone (CaCO3) is broken up and shoveled into a kiln, which is heated to very high temperatures. The high temperatures release carbon dioxide (CO2) from the stone, turning it into calcium oxide. After it is cooled, the compound can be ground into a powder and packaged for sale.
