PROCESS FOR RECOVERY OF IRON OXIDE AND CHLORINEFROM DUST PRODUCED IN CHLORINATION OF TITANIFEROUS ORESABSTRACT OF DISCLOSUREThe dust produced in the chlorination of titaniferous orescomprises essentially particulate ferrous chloride plus solidcontaminants including coke and various metal chlorides andoxides and is oxidized in successive stages at relatively lowtemperatures to recover particulate iron oxide and gaseouschlorine.
