Limestone is not calcined, thus it is does not contribute to an increase in CO 2 emissions. The calcium carbonate supplied through limestone to the system and the extra alumina provided by calcined clay will further react to form alumina phases  .
To reduce to a powder, or to a friable state, by the action of heat; to expel volatile matter from by means of heat, as carbonic acid from limestone, and thus to produce disintegration; as to, calcine bones.
The calcination of calcium carbonate (limestone) is an important step in the regeneration of kraft pulping chemicals and in the production of industrial calcium oxide (quicklime). Better understanding of the kinetics can lead to improved lime kiln efficiencies in both production rate and specific energy use.

Calcination of Limestone . Calcination or calcining is a thermal treatment process to bring about a thermal decomposition. The process takes place below the melting point of the product. The name calcination is derived from the Latin word 'Calcinare' which mean to burn lime. Limestone is a naturally occurring mineral.
DEFINITION. The word "lime" refers to products derived from burnt (calcined) limestone, such as quicklime and hydrated lime. Limestone is a naturally occurring and abundant sedimentary rock consisting of high levels of calcium and/or magnesium carbonate, and/or dolomite (calcium and magnesium carbonate), along with small amounts of other minerals.

Calcination (also referred to as calcining) is a thermal treatment process applied to ores and other solid materials in order to bring about a thermal decomposition, phase transition, or removal of a volatile fraction.The calcination process normally takes place at temperatures below the melting point of the product materials.
Two types of limestone have been calcined at four selected temperatures (900°C, 1000°C, 1100°C, 1200°C), and the produced quicklime was slaked. Chemical, physical, and mineralogical analyses have been performed in limestone, quicklime, and slaked lime samples with the intention of studying the quicklime reactivity.
