The alkali content of pulverized raw material used in the manufacture of cement is economically reduced as the material flows through a furnace system preheating, deacidizing and sintering the material by the introduction of an alkali-reducing, chlorine-containing additive to the material as it flows through one or more of the heating, deacidizing and sintering zones of the furnace.
