Lime

Limestone deposit in the karst of Dinaric Alps near Sinj, Croatia.

Lime is a calcium-containing inorganic material composed primarily of oxides, and hydroxide, usually calcium oxide and/or calcium hydroxide.

Use

The word lime originates with its earliest use as building mortar and has the sense of sticking or adhering. These materials are still used in large quantities as building and engineering materials (including limestone products, cement, concrete, and mortar), as chemical feedstocks, and for sugar refining, among other uses. Lime industries and the use of many of the resulting products date from prehistoric times in both the Old World and the New World.^{[citation needed]} Lime is used extensively for wastewater treatment with ferrous sulfate.

The rocks and minerals from which these materials are derived, typically limestone or chalk, are composed primarily of calcium carbonate. They may be cut, crushed, or pulverized and chemically altered.

Production Methods

Lime (or Calcium oxide) is produced by the thermal decomposition of Calcium Carbonate at temperatures of between 850 and 1200°C. This can be achieved by placing a source of calcium carbonate such as limestone into a simple wood fire for a period of about 1 hour. The resulting lime should be use promptly as it reacts with CO₂ from the atmosphere to reform calcium carbonate.
