METHOD FOR IMPROVING QUALITY OF TITANIUM-CONTAINING FEEDSTOCK Russian patent published in 2018 - IPC C22B1/04 C22B1/08 C01G23/04 C22B7/04 C22B34/12 C01G49/06

Abstract RU 2660876 C2

FIELD: chemistry.

SUBSTANCE: invention can be used in chemical industry. Method for improving the quality of a titanium-containing feedstock involves oxidation of titanium-containing feedstock using gaseous oxygen and simultaneous selective chlorination of impurity metals in titanium-containing feedstock. Impurity chlorides are separated and removed.

EFFECT: invention makes it possible to reduce chlorine losses during the chlorination of titanium-containing feedstock, to obtain feedstock with high titanium content.
