METHOD OF TITANIUM-BEARING RAW MATERIAL PROCESSING Russian patent published in 2010 - IPC C22B34/12 C22B1/08 

FIELD: metallurgy.

SUBSTANCE: method includes preparation of charge, its loading into chlorinator with melt of metals chlorides, chlorination by feeding of chlorine-containing agent through 4 chlorine lead-in into melt of metals chlorides with continuous innovation of melt with receiving of gas-vapor mixture, containing titanium tetrachloride. Then it is implemented saline cleaning of gas-vapor mixture by saline melt of alkaline metals chlorides and cleaning in spray scrubber with condensation of admixtures chlorides in pulp of liquid titanium tetrachloride, used in the capacity of reflux liquid in scrubber, circulation of formed pulp in circuit of spray scrubber in circuit of chlorinator, extraction of titanium tetrachloride by condensation in direct-contact condenser. Additionally chlorination is implemented with usage in the capacity of chlorine-containing agent of chlorine gas and/or anodic chlorine-gas, pulp at first is contact to waste from chlorinator by gas-vapor mixture, and then with melt mirror by metal chlorides. Saline cleaning of gas-vapor mixture is implemented by means of contacting of gas-vapor mixture contact, escaping from chlorinator with surface of melt of alkaline metals chlorides at keeping of melt temperature 350-400°C, concentration of free alkaline metals chlorides 0.5-3.0 wt % and with processing of surface coating of melt by gas stream of inert gas at a rate of feeding 40-120 m³/hour.

EFFECT: intensification of reprocessing.
