Quicklime is produced by heating limestone containing calcium carbonate at a temperature around 1000oc in a "furnace" known as limekiln.
The reaction process of Quiklime: CaCo3 + Heat = CaO + CO2
Applications of Quicklime
Quicklime is widely use in numerous industries for different applicants. For instances :
Steel Making
Quicklime is needed in the steel making for desulphurization and dephosphorization, as well as to keep the slag in a basic order to prevent erosion of the furnace retractory lining.
Nonferrous Uses
CaO is added to adjust the PH and precipitate heavy metal.
Soil Stabilization
The function of lime is to react with the clay fraction in the soil to reduce the susceptibility of the compacted soil to the weakening effect of increasing moisture content.
Sugar
Lime and carbon dioxide added simultaneously to form precipitate of calcium carbonate which entraps colloidal impurities and the carbonated liquor is the filtered to remove the precipitate.
