Abstract
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.
