Limestone – Its Processing and Application in Iron and
It is also a component of synthetic slag. Limestone is normally used in three forms. These are (i) raw limestone which is also the natural form of limestone, (ii) calcined limestone or quicklime, or simply lime, and (iii) as hydrated lime. When limestone is used as a fluxing material then it is used as either raw limestone or as calcined limestone.
