METHOD FOR PRODUCING CALCINED CLAY
A method for producing calcined clay having desired colour characteristics. The method includes: a step of calcining a clay in a calcination furnace, the calcination step being carried out under stoichiometric or oxidising conditions, and a step of reducing iron (III) oxides present in the calcined clay in a reduction system separate from the calcination furnace, this reduction step being carried out by injecting a reduction gas, containing hydrogen atoms and placed in direct contact with the calcined clay.
