FIELD: chemistry.
SUBSTANCE: method comprises homogenizing a mixture of raw components containing finely divided limestone, granulating the mixture of raw components, calcining them, and decarbonizing the granules. The granulation of a mixture of raw ingredients comprising 2-4 wt % of quenched calcium lime, 89-91 wt % of finely divided limestone, and 7 wt % of water is carried out by pressing in hydraulic presses to obtain granule-cylinders with a height and diameter of 20 mm. The granules are loaded into the carbonization chamber and the exhaust gases of calc-calcining furnace containing not less than 20% of CO2. An artificial carbonization of the granules and their calcination to a decarbonization temperature of limestone of 950-1100°C.
EFFECT: improving the quality of lime and improving the environmental situation of the territories.
