About Limestone. Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO3) in the form of the mineral calcite or aragonite. It is a kind of stone widely found in nature. Limestone can be directly processed into stone using crushing equipment and fired into quicklime. Quicklime absorbs moisture or adds water to become hydrated lime.

The Rock Cycle is a model describing the formation, breakdown, and reformation or restructuring of rock as a result of sedimentary, metamorphic, and igneous processes. There are three types of rock, each formed by a different process: Igneous Rock. The word igneous comes from the Latin word ignis, meaning fire.
