The major use of quicklime is in the basic oxygen steelmaking (BOS) process. Its usage varies from about 30 to 50 kilograms (65–110 lb) per ton of steel. The quicklime neutralizes the acidic oxides, SiO 2, Al 2 O 3, and Fe 2 O 3, to produce a basic molten slag. Ground quicklime is used in the production of aerated concrete blocks, with densities of ca. 0.6–1.0 g/cm 3 (9.8–16.4 g/cu in).

Apart from the lime hydrate production, the hydrators also serve to process other materials. During their production, quicklime was formed as an ingredient contained in these materials, for example as a result of a burning process, and such quicklime has to be transformed into hydrated lime before it can be further processed or put into stock.

Lime is produced in a thermal process known as calcination according to the reaction. CaCO3 + Heat = CaO + CO2. Heat causes the calcium carbonate to lose a molecule of carbon dioxide. The end product is calcium Oxide, better known as unslaked lime or quicklime. At Ndola Lime this process is achieved in oil-fired rotary and vertical kilns.

Quicklime Production: The production of high calcium quicklime (calcium oxide) requires a large amount of heat, which is generated in the kiln environment. The quarried and sized high calcium limestone travels through a rotary kiln and is subjected to these high temperatures where the calcium carbonate begins to decompose into calcium oxide and carbon dioxide.
