is fed into a rotary kiln where it is dried and heated counter-currently by combustion gases from an oil or gas burner at the other end of the kiln. As the mud temperature reaches about 800oC (1470oF) in the calcination zone of the kiln, CaCO3 decomposes into CaO and CO2 (Reaction 3). The resulting CaO or reburned lime is reused in the causticizing
