A METHOD OF PRODUCING METAL CHLORIDE WHICH COMPRISES CONTACTING A MIXTURE CONTAINING CARBON AND HAVING AS ITS PRINCIPAL METAL OXIDE COMPONENT METAL OXIDE SELECTED FROM THE GROUP CONSISTING OF IRON OXIDES, TITANIUM OXIDES AND MIXTURES THEREOF WITH HYDROGEN CHLORIDE, CONVERTING SUCH METAL OXIDE TO METAL CHLORIDE BY REACTION OF HYDROGEN CHLORIDE AND METAL OXIDE IN THE PRESENCE OF CARBON, MAINTAINING SUFFICIENT CARBON IN THE MIXTURE DURING SAID CONVERSION TO COMBINE CHEMICALLY WITH A QUANTITY OF OXYGEN EQUIVALENT TO THAT LIBERATED BY THE CONVERSION OF METAL OXIDE TO METAL CHLORIDE AND TO INSURE THAT THE HYDROGEN VALUES OF THE REACTED HYDROGEN CHLORIDE APPEAR IN THE PRODUCTS OF REACTION AS ELEMENTAL HYDROGEN, OBTAINING CONCURRENTLY WITH THE FORMATION OF METAL CHLORIDE AND OXYGEN VALUES OF SUCH CONVERTED METAL OXIDE AS CARBON OXIDE AND THE HYDROGEN VALUES OF THE REACTED HYDROGEN CHLORIDE AS ELEMENTAL HYDROGEN IN THE PRODUCTS OF REACTION WHEREBY THE PRODUCTION OF WATER FROM SAID HYDROGEN AND OXYGEN VALUES IS PRECLUDED.
