Hydrolyzable titanyl sulphate solutions by decomposition of ternary raw material mixtures |
| abstract |
A process for the preparation of a hydrolyzable titanyl sulphate solution comprising adding sulphuric acid having a concentration greater than about 86% to a ternary mixture of two slags and an ilmenite to bring the proportion by weight of H2SO4 to TiO2 to from about 1.7:1 to 2.2:1 and adding water, dilute sulphuric acid or oleum in amount sufficient to bring the H2SO4 concentration to from about 86 to 96%, thereby to form the titanyl sulphate solution, the first slag having a TiO2 content greater than about 80% and a Ti(III) content of about 22 to 40%, the second slag having a TiO2 content of about 60 to 80% and a Ti(III) content of about 5 to 15%, and the ilmenite having a ratio of Fe(III) to Fe(II) of from about 1:1 to 10:1, the slags and ilmenite being present in such proportions that the ternary mixture of raw materials obtained has a molar ratio of Ti(III) to Fe(III)>/=1.4. |
