Beschreibung
Zusammenfassung:	FIELD: recovery of titanium from leucoxene concentrates in concentration of oil-bearing silico-titanic ores. SUBSTANCE: method includes roasting of leucoxene concentrate in presence of modifying additives in form of iron oxide compounds in amount of 2-3% in t5erms of TiO2 (of concentrate weight) at roasting temperature of 1450-1525 C. Sinter is cooled, ground and subjected to preliminary desliming. Autoclave leaching is carried out with NaOH solutions. Leached pulp is filtered into silicate solution and titanium-containing product, with desliming of the latter. EFFECT: increased content of Fe2O3 in concentrated product with reduced volume of material flows in leaching. 2 tbl
