Limestone

A sedimentary rock composed of calcium carbonate in the form of mineral calcite.

Calcite

The mineral form of calcium carbonate found in limestone, marble, and chalk.

Marble

A type of limestone that is formed when limestone is subjected to high pressures and temperatures, resulting in the formation of crystals of calcium carbonate in the rock.

Chalk

A form of limestone made of calcite.

Brachiopods and Crinoids

Animal structures that contribute to the formation of most other limestones through the accumulation of their debris.

Cement

A material made from limestone that is used in construction.

Road building

The use of limestone in the construction of roads.

Glass making

The utilization of limestone in the production of glass.

Extraction of iron

The process of using limestone in the extraction of iron from its ores.

Neutralisation of acid soil

The application of powdered limestone to neutralize acidic soil due to its affordability.

Lime manufacture

The process of thermally decomposing calcium carbonate to produce calcium oxide (lime) and carbon dioxide, which takes place in a lime kiln.

Quicklime or Lime

The calcium oxide produced during the thermal decomposition of calcium carbonate.

Soil acidity neutralization

The use of calcium oxide (lime) to spread on fields to neutralize soil acidity and improve water drainage in clay-rich soils.

Neutralization of industrial waste products

The utilization of calcium oxide (lime) to neutralize industrial waste products such as FGD (flue gas desulfurization).

Drying agent

The application of calcium oxide (lime) as a drying agent in various industries and in the manufacture of mouthwash.
