Calcined Lime

Calcined lime (burnt lime) is produced by calcining limestone (CaCO₃). Calcination is the process of removing CO₂ from limestone. Heating limestone to approximately 1200°C yields calcium oxide, also known as quicklime (CaO). In domestic production, less than 3 million tons of limestone are used in the metallurgical industry, with about half consumed in steel production.

Calcined lime is a crucial fluxing agent in steelmaking. However, lime used in the steel industry must have the highest possible CaO purity and minimal impurities such as SiO2, sulfur, and phosphorus.

Applications:

1. Construction Industry:
   • Used in cement production and as a component in lime and gypsum mortars.
2. Metallurgy:
   • Acts as a flux in steelmaking to remove impurities and is used in non-ferrous metal refining.
3. Chemical Industry:
   • Serves as a raw material in the production of various chemicals and for pH control in chemical processes.
4. Water Treatment:
   • Used for water softening and pH adjustment in treatment plants.
5. Environmental Applications:
   • Used in flue gas desulfurization to reduce sulfur dioxide emissions and in soil stabilization to improve soil properties.
6. Agriculture:
   • Corrects soil acidity and serves as a calcium supplement in animal feed.
7. Food Industry:
   • Used in food processing for water treatment and as a clarifying agent.
