The main feedstock of the titanium industry is titanium–magnetite ore. Such ore processing includes production of ilmenite concentrate which is then melted with coal to produce titanium slag which is a titanium tetrachloride stock. The more commercially and technologically beneficial feedstock is a rutile concentrate. Its source may be the ore from the Yarega oil–titanium deposit with the content of TiO2 up to 10 %. The authors propose a processing method for the quartz–leucoxene concentrate which is the middlings of such ore beneficiation. The method assumes desilication of the concentrate by means of high-temperature roasting with chloride agents. Roasting leads to recrystallization, regeneration of quartz–rutile aggregates and their size increase, as well as to removal of chemical impurities from rutile crystals. Beneficiation of the milled mixture allows producing pure rutile concentrate.
