· Limestone is the most common sedimentary rock and is composed of calcium carbonate. Limestone rock is often one of high purity, with a calcium carbonate content of over 95%, and not uncommonly 99% (Trudgill, 1985). The initial stage of the production is the mining of the limestone. This is accomplished by either strip mining or underground mining.
