Calcium carbonate. Three types of calcium carbonate-containing rock are excavated and used by 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.Get Price
May 01, 2014 Purity – calcium carbonate equivalent (CCE) The purity of limestone is expressed as calcium carbonate equivalent (CCE). It is a laboratory measure of how much calcium carbonate reacts in a given sample. Limestone should have a CCE of at least 90 percent. Liming material CCE can range from 50 to 175 percent.Get Price
