Abstract

En fremgangsmåte for fremstilling av tltandloksld ifølge sulfatfremgangsmåten, l det de tltanholdlge råstoffene blir oppsluttet l nærvær av metallisk Jern og svovelsyre, deretter hydrolysert og det oppståtte tltandloksldhydratet blir kalslnert, er beskrevet.A process for preparing the titanium oxide according to the sulfate process, in which the titanium-containing raw materials are digested in the presence of metallic Iron and sulfuric acid, then hydrolyzed and the resulting titanium oxide hydrate is calcined, is described.
