Abstract: The disclosure is directed to a process for producing separable iron and titanium oxides from an ore containing titanium oxide and ferric oxide, comprising: (a) forming agglomerates comprising carbon-based materials and the ore, the quantity of carbon of the agglomerates being sufficient for, at an elevated temperature, reducing ferric oxide to ferrous oxide and forming a ferrous oxide-rich molten slag, (b) introducing the agglomerates onto a carbon bed of a moving hearth furnace; (c) heating the agglomerates in the moving hearth furnace to a temperature sufficient for reducing and melting the agglomerates to produce a ferrous oxide-rich molten slag; (d) metallizing the ferrous oxide of the molten slag by reaction of the ferrous oxide and the carbon of the carbon bed at a furnace temperature sufficient for maintaining the slag in a molten state; and (e) solidifying the slag after metallization of the ferrous oxide to form a matrix of titanium oxide-rich slag having a plurality of metallic iron granules distri

Abstract: The disclosure is directed to a process for isolating solids from a purification purge stream comprising an impurity present as a solid, wherein the purification purge stream is substantially free of chlorides other than titanium tetrachloride and vanadium chloride, the process comprising the steps of: (a) atomizing the purification purge stream comprising titanium tetrachloride as a liquid and an impurity present as a solid; (b) drying solids in the atomized purification purge stream by contacting the atomized stream with a titanium tetrachloride vapor stream such that the combined streams reach a temperature of at least about 140° C. to vaporize the liquid titanium tetrachloride, wherein the titanium tetrachloride vapor is substantially free of chlorides other than those of titanium and vanadium, and substantially free of non-condensable gases comprising CO, CO2, N2, or mixtures thereof; and (c) separating the impurity present as a solid from the vaporized titanium tetrachloride.

Abstract: The present invention relates to a process for recovering chlorine from a feed stream containing metal chlorides using a tubular reactor wherein a hot oxygen containing gas has an initial velocity such that the resulting velocity of the bulk gas formed from mixing the oxygen containing gas with the metal chloride feed stream and a scrubs feed stream is sufficient to remove wall deposits as fast as such deposits are formed.
