The pellets are then coated with a non-agglomerating material selected to permit firing of the mixture without pellet agglomeration at a temperature above 1300 DEG C. The coated pellets are fed to a kiln and fired at a temperature above 1300 DEG C. before being discharged from the kiln. At least some of the heat of firing the pellets is recovered and recycled to the kiln.
