METHOD OF PREPARING OF TITANIUM SULFATE SOLUTION Russian patent published in 1994 - IPC

Abstract RU 2021205 C1

FIELD: chemical technology. SUBSTANCE: 100 g Canadian titanic slag is treated with 140 g concentrated sulfuric acid, and water is added to melt prepared. Then polyvinyl alcohol is added at concentration 0.05 wt.-% (at calculation for the basic substance). Melt is leached at stirring with compressed air, filtered. Titanium extraction into solution is 95%. Stability of solution is 650 650cm³. Method is used for preparing of titanium sulfate solutions used for titanium dioxide isolation. EFFECT: improved method of titanium sulfate solution preparing. 1 tbl, 10 ex
