Limestone is a versatile commodity used to create products for agricultural, environmental, and industrial purposes. Cement, paint, soil amendments, and even breakfast cereals all contain this resourceful mineral. Of course, mined limestone is not naturally found in a suitable form for many of these products.

2 emissions impacts of cement production processes. Mining and Quarrying The most common raw material used for cement production is limestone. In most cases, these raw materials are mined from a quarry near the cement plant. The limestone provides calcium oxide, and clay, shale, and other materials provide the silicon, aluminum, and iron oxides

Cement manufacturing process in summary. Portland cement is manufactured by heating limestone (calcium carbonate) with other materials (such as clay) to 1,450 °C (2,640 °F) in a kiln, in a process known as calcination that liberates a molecule of carbon dioxide from the calcium carbonate to form calcium oxide, or quicklime.
