Abstract

1431552 Upgrading Ti ores LAPORTE INDUSTRIES Ltd 22 March 1973 [7 Jan 1972] 50276/75 Divided out of 1431551 Heading C1N A weathered ilmenite or leucoxene is activated to render it more readily acid leachable by heating at 600-950‹ C. in reducing or oxidizing conditions, the heating being discontinued before the proportion of Fe which has undergone a change in oxidation state exceeds <SP>1</SP>/ 15 by weight. When treated under oxidizing conditions, the maximum treatment period is 45 minutes and an atmosphere containing not more than 12% vol., preferably 4-7%, is used. The treatment preferably lasts at least 10 minutes. When the ore is treated in reducing conditions, it may be subjected to oxidation prior to leaching by heating in air at 700-850‹ C. to convert all or part of ferrous content to ferric. The treated ore may be subjected to a magnetic separation prior to leaching. Leaching is preferably performed with HCl, optionally containing Fe<SP>2+</SP> ions, at above 100‹ C. in a counter current fluidized bed process. The leached solid may be calcined at 600-700‹ C. for ¢-2 hours and then chlorinated under fluidized bed conditions to TiCl 4 from which pigment grade TiO 2 may be made.
