hydration process or lime slaking. The hydration of CaO, commercially referred to as quick lime, is an exothermic process releasing a great quantity of heat. This hydration process when done with just the right amount of water is called “Dry Hydration.” In this case the hydrate material is a dry powder. If excess water is used for hydration, the process is called “Slaking.” In this,

Lime Manufacturing and the Lime Slaking Process. Quicklime, often referred to as either calcium oxide (CaO) or lime, is manufactured by heating the raw ingredient ‘limestone’ or ‘calcium carbonate’ in large kilns. This process removes CO2 that is trapped in the stone leaving behind CaO and other minor mineral constituents. This CaO molecule is what we consider to be high calcium,
