Abstract: Quicklime is used in several applications, mainly in the production of hydrated lime, which is a major component in the chemical and food industries (sugar, food drinks, and manufacture of some medicines, leather, paper, plastics and petrochemicals). The quick lime production process including extraction and preparing of limestone and burning it at high temperature (1200 - 1500) ?C in a kiln, then cooling it by air, storing portion of it, and the remaining portion is used to create slaked lime by reacting with water. The objective of project is produce high quality of quicklime and slaked lime from limestone. Three samples of limestone were taken from three different places in the Sudan: Aljabalain, Kasala and Red sea. The three samples were analyzed and the Red sea sample was excluded because the percentage of calcium carbonate is low. The other samples were burned in the kiln at temperature 1200 c and analyzed, the result of analysis showed that the limestone of Aljabalain is the best because it contains a high percentage of calcium carbonate. Quicklime and slaked lime were produced with a high degree of purity.
