A hydrometallurgical technology for processing a titanomagnetite concentrate is proposed and substantiated. The technology includes the decomposition of the concentrate in a weakly concentrated sulfuric acid solution in the presence of a sulfonic cation-exchange resin in the H+ form with the transition of the major portion of metals of the titanomagnetite concentrate to the sorbent and the formation of an ilmenite-enriched residue; the desorption of metals from the saturated sulfonic cation-exchange resin with a 5 M solution of sodium chloride; the fractional hydrolytic precipitation and separation of titanium hydroxide, iron hydroxide enriched in vanadium, pure iron hydroxide, and a mixture of iron and manganese hydroxides; and the regeneration of the sulfonic cation-exchange resin. The optimum parameters of the particular processes are determined. Sulfuric acid is weakly consumed and no liquid wastes are formed in the technology. [ABSTRACT FROM AUTHOR] |
