Abstract

Process for the thermal treatment of minerals in which the material is fed successively by areas of preconditioning, pre-treatment and final treatment, with hot gases charged with powder from the final treatment zones to the pre-burn zone, characterized in that it comprises the steps of discharging a part of said gases in said pre-burn zone in contact with and through the material in said zone and then removing them from that pre-burn zone; diverting another part of said gases in the pre-burn zone of the materials contained therein, taking it out of the pre-burn zone to reduce contamination of the material in said zone with undesirable mineral components; mix air with said deviated part of gases in order to produce a colder mixture; remove the unwanted mineral components from said colder mixture; and passing said mixture to said pre-conditioning zone.
