A process for producing chlorine and iron oxide from iron chloride (which may be generated as a by-product of the direct chlorination of titaniferous ores) comprises the steps of converting ferrous chloride to ferric chloride by reaction with chlorine, separating the solids from the gaseous products, reacting the gaseous ferric chloride with oxygen, condensing unreacted ferric chloride onto iron oxide particles, separating the gaseous products from the iron oxide particles and recycling the iron oxide particles to the oxidation or condensation step.
L'invention concerne un procédé de production de chlore et d'oxyde de fer à partir de chlorure de fer (qui peut constituer un sous-produit de la chloration directe de minerais titanés). Ledit procédé consiste à convertir le chlorure ferreux en chlorure ferrique en le faisant réagir avec du chlore, à séparer les solides des produits gazeux, à faire réagir le chlorure ferrique gazeux avec de l'oxygène, à condenser le chlorure ferrique non converti sur des particules d'oxyde de fer, à séparer les produits gazeux des particules d'oxyde de fer et à réintroduire les particules d'oxyde de fer aux stades d'oxydation ou de condensation.
