When water (H 2 O) is added very carefully to quicklime/burnt lime/calcium oxide (CaO), a further chemical process called hydration (also called slaking) takes place and the resulting material is called hydrated lime or slaked lime and is mainly calcium hydroxide [Ca(OH) 2]. The hydration/slaking chemical reaction is exothermic - it releases ...

FACTORS OF LIME SLAKING The aim of the slaking reaction is to produce a slurry containing calcium hydroxide particles with high surface areas. Because particles with higher surface areas are more highly reactive, such slurries are more efficient in the end-use process, creating the required result from the minimum input of lime.

4.2 Energy use and emissions. The lime production process is energy intensive and results in CO 2 emissions from both mineralogical transformation process and energy used. The production of one tonne of lime entails the emission of around 1.2 tonne of CO 2 (Ochoa George et al., 2010; Sagastume Gutiérrez et al., 2012).This makes lime one of the products with the highest …

In some lime plants, the resulting lime is reacted (slaked) with water to form hydrated lime. The basic processes in the production of lime are: (1) quarrying raw limestone; (2) preparing limestone for the kilns by crushing and sizing; (3) calcining limestone; (4) processing the lime further by hydrating; and

How is industrial mineral lime made? Quicklime (calcium oxide) is created by heating limestone or chalk (calcium carbonate) in a kiln to temperatures of over 900 deg C. This process releases carbon dioxide and is known as Calcination. Hydrated or slaked lime (calcium hydroxide) is produced when water is added.

Slaked Lime is known to be an insoluble compound in water. It is also observed that the dissolution of Slaked Lime in water is an exothermic process and hence according to Le Chatelier's principle the lowering of temperature tends to favor the heat that is liberated through the process of dissolution and increases the equilibrium constant of dissolution.
