Precipitated calcium carbonate is purer than ground calcium carbonate.

Calcium carbonate - The Essential Chemical Industry

Three types of calcium carbonate-containing rock are excavated and used by industry. They are line, chalk and dolomite. Line 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.
