how to process quick lime

Calcium oxide - Wikipedia

• The major use of quicklime is in the basic oxygen steelmaking (BOS) process. Its usage varies from about 30 to 50 kilograms (65–110 lb) per ton of steel. The quicklime neutralizes the acidic oxides, SiO2, Al2O3, and Fe2O3, to produce a basic molten slag. • Ground quicklime is used in the production of aerated concrete such as blocks with densities of ca. 0.6–1.0 g/cm (9.8–16.4 g/cu in).
