Limestone is a sedimentary rock composed largely of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). Most limestone is composed of skeletal fragments of marine organisms such as Coral, Forams and Molluscs.
Limestone Lumps contain more than 50% CaO & that is suitable for Steel and Cement Industry. The Limestone Lumps are used as a raw material for manufacturing Quicklime (Calcium Oxide), Slaked Lime (Calcium Hydroxide), Cement & Mortar.
