Abstract

Ores, materials and minerals, containing iron oxide in the ferric state are treated in a non-reducing atmosphere with a chlorinating gas to separate out vaporous ferric chloride, preferably at above 900 DEG C., and the chlorinating gas is then regenerated, preferably above 300 DEG C., e.g. 700-750 DEG C., in a separate reactor by conversion of the ferric chloride and oxygen to ferric oxide, which is separated, and chlorine, which is returned to the first reactor. If the iron is originally present in a state of oxidation, lower than ferric, the material is pretreated with air at elevated temperature, e.g. above 500 DEG C., especially 1000 DEG C., to oxidize the iron to the ferric state. In examples, low grade iron ores were treated for the recovery of ferric oxide, and ilmenite was treated to obtain ferric oxide free from titanium oxide and titanium oxide free from ferric oxide.
