PREPARATION METHOD FOR DIRECTLY SYNTHESIZING TITANIUM DIOXIDE FROM TITANIUM-RICH ORGANIC PHASE PREPARED FROM ILMENITE

摘要

The present invention relates to a method for directly synthesizing titanium dioxide from a titanium-rich organic phase prepared from ilmenite, and more particularly to a method in which a titanium-rich acidolysis solution is obtained by an efficient ore dissolving technology, titanium ions are transferred to the organic phase by means of an effective titanium extractant to obtain a high-purity and titanium-rich organic phase, and then the titanium dioxide is directly synthesized in the organic phase. With this method, the dissolution rate of ilmenite can be effectively improved, the process flow is shortened and production costs are reduced, and titanium dioxide with high yield and high quality is obtained.
