Abstract A novel improvement in the process for the carbo- chlorination of kaolinitic ores is provided wherein the improvement comprises adding catalytic amounts of boron chloride to the carbo-chlorination step which results in the catalyzed and controlled chlorination of alumina and silica. Preferably, about 0.3 to 5.0 percent of boron chloride per volume of chlorine is added to the chlorina- tion step and in combination with from 5 to 40 percent or more of reductant carbon to provide a conjoint action wherein preferential chlorination of alumina over silica is obtained at low levels of boron chloride and reductant and total chlorination of both alumina and silica are ob- tained at high boron chloride and reductant levels.
