METHOD FOR PRODUCING CALCINED CLAY
Disclosed is a method for producing calcined clay having desired colour properties, wherein the method comprises: - a step of calcinating a clay in a calciner (6), the calcination step been carried out under stoichiometric or oxidising conditions; - a step of reducing iron III oxides present in the calcined clay in a reduction system (7) different from the calciner (6), this reduction step been carried out by injection (15) of a reducing gas containing hydrogen atoms and placed in direct contact with the calcined clay.
