Abstract
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.
期刊介绍：
Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
