Title:
METHOD FOR REFINING TITANIUM-CONTAINING MATERIAL
Document Type and Number:
Japanese Patent JPH0688149
Kind Code:
A
Abstract:
PURPOSE: To remove the radioactive element component incorporated into a titanium-contg. material which is a raw material for production of titanium tetrachloride by a simple means.
CONSTITUTION: The titanium-contg. material is subjected to a heating treatment in an aq. mineral acid soln. in such a manner that the total removal rate of an uranium component and throium component is ≥60% and that the fine grain components of 200 meshes in the treated product attain ≤1%. The radioactive element components are effectively removed while the generation of the fine-grained components and the degradation in the yield of TiO2 are suppressed.
