(57) The aim of the method according to the invention is to produce a stream of calcinated solids rich in CaO and a pure or almost pure stream of CO2 from a solid stream rich in CaCO3, by means of a stream of solids heated at a very high temperature by a process of oxidation of said solids with air. The stream rich in CaO can be used to supply clinker kilns in cement works or for processes for harnessing CO2.
