摘要： The invention relates to a process for the preparation of phosphoric-acid-containing solutions, in which process the solution is converted into a solid by adding aluminium compound. Said solid can readily be disposed of since it is not water-soluble. Said process is particularly suitable for preparing phosphoric-acid-containing solutions from metal processing. The invention also relates to a device (10) for carrying out the process which has a mixer tube (12) with a longitudinal axis (M), an inlet (14) and an outlet (16). In a central area, at least two fluid feed nozzles (18 and 20) open into the mixer tube inlet (14) and in relation to the inlet cross section thereof. At least one gas feed nozzle (22) arranged radially outside the fluid feed nozzle (18 and 22) also opens into the mixer tuber inlet (14). The longitudinal axis (G) of each gas feed nozzle (22) is inclined to the central longitudinal axis (M) in such a manner that the said axes do not intersect. The angle between each longitudinal axis (G) and the central longitudinal axis (M) is at least 5 DEG .

摘要： A process is disclosed for regenerating an aqueous acid halide leachant from a spent aqueous metal halide leach liquor. The process comprises introducing into a fluidized bed or spray roaster a hydrocarbon fuel, an oxygen-enriched oxidizing gas and the aqueous metal halide leach liquor; pyrohydrolyzing the aqueous metal halide leach liquor by combustion of the hydrocarbon fuel with the oxygen-enriched oxidizing gas to produce an acid halide-containing gas fraction and a metal oxide-containing solid fraction; separating the gas fraction from the solid fraction, recovering heat energy from the acid halide-containing gas fraction and absorbing the gas fraction in water to produce the aqueous acid halide leachant. The oxygen-enriched oxidizing gas has an oxygen concentration of greater than about 21 percent by volume, preferably greater than about 50 percent by volume, more preferably greater than about 80 percent by volume, and even more preferably greater than about 90 percent by volume. Preferably, the aqueous metal halide is iron (II) chloride or nickel chloride. Despite higher cost associated with the oxygen-enriched oxidizing gas as compared to air, the process is capable of being operated more economically and efficiently than an equivalent air roasting pyrohydrolysis, and produces a higher concentration aqueous halide leach liquor, which is preferred in metallurgical processes such as solvent extraction and solids leaching.
