An improved dilute phase chlorination procedure characterized by providing extremely finely divided oxygen-containing metallic material and a carbonaceous material co-milled together to a particle size size of less than 20 microns. The finely divided charge material is introduced into a tubular reaction zone, preferably at the bottom, with the gaseous chlorination agent where reaction occurs at a temperature above 800. degree. C. for a period of time sufficient to fully react the chlorinating agent in a single pass. Metal chloride is recovered from the tubular reactor and, most advantageously, there is little or no need to separate any dusty unreacted solid material from the off-gases for recycle to the chlorination zone.

Vapor feed containing titanium tetrachloride and ferric chloride vapor is contacted with sodium chloride for complexing said ferric chloride as liquid sodium ferric chloride salt complex while leaving titanium tetrachloride as vapor residue. The salt complex is reacted with molecular oxygen for providing recovered chlorine gas product. Such gas can be recycled to said complexing operation for providing a high grade of chlorine and titanium tetrachloride-rich product. Substantially complete chlorination of ilmenite is a prime source of said vapor feed.

A low temperature (less than 800. degree. C. ) process for chlorinating titaniferous material in a fluidized bed is disclosed. A porous carbon reductant having micropores with a pore diameter of less than 20 A is utilized together with conventional titaniferous materials and conventional chlorine sources to achieve reaction at the present low temperatures.
