FIELD: metallurgy.
SUBSTANCE: method comprises mixing a concentrate with a HCl solution to obtain a leached residue. Further, neutralisation is carried out with water of the residue washed with dilute alkaline solution, filtering the neutralized slurry to form a neutralized residue which was mixed with NaOH solution, and washed with alkali to desilication. Then washing is carried out with water, dilute sulfuric acid and adjusting the pH to 5-6, followed by filtration and drying to obtain a filtered residue of the titanium residue.
EFFECT: method for the separation and extraction of silver, titanium and iron from mentioned concentrates.
