摘要： A process of treating metal chloride wastes produced by chlorination of titanium ore comprises the steps of:(a) leaching said metal chloride wastes in a hydrochloric acid (HCl)-containing solution to obtain a solution containing solids and dissolved metals,(b) separating said dissolved metals from said solids present in the solution obtained in step (a) to obtain a liquid and a residue,(c) selectively precipitating the metals as their hydroxides by adding a neutralizing agent to the liquid obtained in step (b),(d) separating the precipitate of metal hydroxides obtained in step (c) from the liquid to obtain a residue, and(e) dewatering the residue obtained in step (d).

摘要： In the process for recovering gallium from aqueous, alkaline solutions by adsorption of the gallium on to bead-polymerized synthetic resins impregnated with 8-hydroxyquinolines and elution thereof with aqueous acids, the synthetic resins employed according to the invention are macroporous polydivinylbenzene or macroporous divinylbenzene copolymers which have been obtained by bead polymerization of divinylbenzene or mixtures of aromatic mono-, di- and/or trivinylbenzenes containing at least 50% by weight of divinylbenzene, in the presence of methyl isobutyl ketone, and which have been loaded with 160-190 g of Kelex 100 per liter of resin; in addition the resin is washed with sodium hydroxide solution after the elution step and before the commencement of each individual service cycle.
