Africa, isolated high-grade deposits of limestone occur. This has resulted in lime production being limited to a few plants, with a fairly large output. Thus some South African plants are, by global standards, considered large production plants. Secondly, South Africa's well-developed uranium and gold operations are strongly dependent on
Calcium oxide, CaO, also known as lime or more specifically quicklime, is a white or grayish white solid produced in large quantities by roasting calcium carbonate so as to drive off carbon dioxide. At room temperature, CaO …
Chemical. Calcium oxide can be reacted, or slaked, with water, releasing large amounts of heat and producing calcium hydroxide. In open air, it reacts with water vapor and carbon dioxide, slowly converting to calcium carbonate over time. It is used as a component of many cement mixes, and can be reacted with acids to form calcium salts.

The iron oxides are reduced in the upper region of the furnace. In the middle region, limestone (calcium carbonate) decomposes, and the resulting calcium oxide combines with silica and silicates in the ore to form slag. The slag is mostly calcium silicate and contains most of the commercially unimportant components of the ore:
