Calcination of Limestone – IspatGuru

2013-5-2  The production of good quality lime depends upon the type of kiln, conditions of calcination and the nature of the raw material i.e. limestone. At relatively low calcination temperatures, products formed in the kiln contain both unburnt carbonate and lime and is called ‘under-burnt’ lime.

Lime Calcination SpringerLink

Lime is one of the most widely used and cheapest alkalizing agents employed worldwide. It is often applied in chemical processes in a slaked or calcium hydroxide or slurry form. The term “calcinations of limestone” refers to the process of thermal decomposition into quick lime and carbon dioxide. It is frequently referred to as “calcinations.”
