Lime Stone
Limestone is a sedimentary rock primarily composed of calcium carbonate (CaCO₃) in the form of the mineral calcite.
- Crushed limestone is a primary component in concrete and asphalt, providing foundational strength and stability for roads, bridges, and buildings.
- Limestone (calcium carbonate) is a key ingredient in glass production. It acts as a stabilizer, preventing glass from being soluble in water and adding to its hardness and durability.
- Limestone is the primary raw material for cement production. It is heated in a kiln with clay and other materials to produce clinker, which is then ground to make cement.
- Ground limestone is added to animal feed to provide a source of calcium, which is essential for bone development and overall health in livestock.
- Limestone is used as a flux in the smelting of iron ore in blast furnaces. It helps remove impurities such as silica, phosphorus, and sulfur from the molten iron, forming a slag that can be easily separated.
