摘要： A method of removing aqueously soluble salt by-products produced by the treatment of raw titanium dioxide particles to add a finish thereto. The finished titanium dioxide particles with the salt are subjected to demineralization with mixed bed ion exchange resins to produce finished titanium dioxide particles substantially free of salt and salt forms of ion exchange resins. The finished titanium dioxide particles are recovered and the salt forms of ion exchange resins are regenerated to produce recoverable salt and reusable resins.

摘要： In a process for the removal and pressure reduction of a high pressure, high temperature slurry from a process vessel, the slurry is mixed with a make-up liquid in a temperature treatment vessel to form a diluted slurry, which is passed through a cooling apparatus, and a recycle portion of the diluted slurry is recycled to the temperature treatment vessel. Another portion of the cooled diluted slurry solution is flashed to a preselected reduced pressure through a pressure reducing valve, and this portion is passed to a stripping vessel for concentrating and producing a slurry product. In operation, plural slurry gravity settling vessels may be connected to a single heat treatment vessel, thereby effectuating slurry pressure reduction across a single pressure reducing valve.

摘要： In the manufacture of particulated metal oxides by the vapor phase oxidation of volatile metal halides, hot gaseous effluent streams are produced which, after separation of the desired particulated metal oxide therefrom, contain residual amounts of the particulated metal oxide as well as unreacted, volatile metal halide and halogen gas. The method of this invention provides for the recovery of these materials, individually, through a succession of contacting and separating steps utilizing a recycle stream of previously recovered, unreacted, liquid metal halide. Utilization of the recycle stream of metal halide provides for both evaporative cooling of the hot gaseous effluent stream to permit recovery of the residual particulated metal oxide therein and scrubbing of the resulting off-gas to recover the unreacted volatile metal halide therein as a liquid and provide a gas phase containing the by-product halogen gas. The recovered unreacted volatile metal halide liquid constitutes the recycle stream of liquid metal halide used in the process. The gas phase is subjected to a further scrubbing to separate and recover therefrom any remaining unreacted, volatile metal halide.

摘要： A continuous process for recovering substantially pure aluminum chloride from chlorination products of aluminum ore. The chlorination products are contacted with a first selective solvent to dissolve a substantial portion of the aluminum chloride and some ferric chloride. The solvent is separated from the chlorides which then are treated to produce a ferric chloride-rich stream and an aluminum chloride-rich stream in which the aluminum chloride to ferric chloride ratio is higher than the ratio prior to solvent separation. The aluminum chloride-rich stream is contacted with a second solvent to dissolve any ferric chloride present and saturate the solution with aluminum chloride. Aluminum chloride in excess of that soluble in the second solvent separates as a substantially pure solid phase. The solution is separated from solid phase and recycled in process to recover additional aluminum chloride.

摘要： An improved process for the production of synthetic rutile from ore containing titanium and iron, such as ilmenite ore, by a multi-step procedure employing controlled reduction, controlled oxidation and acid leaching. More specifically, the ilmenite ore first is reduced thermally such that substantially all of the iron (III) present has been converted to iron (II) and some metallic iron. The reduced ore then is oxidized with an oxidizing gas substantially free of elemental oxygen to convert the metallic iron to iron (II) without the substantial formation of iron (III). The oxidized ore then is leached to remove the iron (II) and calcined to produce synthetic rutile. The synthetic rutile so produced contains in excess of 92 percent titanium dioxide and less than 2 percent iron (III), by weight. Often, the synthetic rutile contains less than 1 percent total iron by weight.
