ABSTRACT:
The invention relates to a process for the decarbonation of minerals, in powdered form, in a fluidized bed. For example, the process applies to the production of quick lime and/or magnesia from lime stone and/or dolomite fines which are not rendered sufficiently valuable at present.
The process comprises recycling a portion at least of the carbon dioxide produced to be used as sole fluidizing gas, the fluidized bed being heated to the desired decarbonation temperature by direct heat supply within the fluidized bed by means of electric devices.
Production of decarbonated minerals and of CO.sub.2.
