Abstract

Det er beskrevet en fremgangsmåte for fremstilling av titandloksyd ved sulfatfremgangsmåten, hvorved den ved vasking av hydrolysatet dannede væsken fraksjoneres og de fortynnede fraksjonene tilbakeføres l prosessen, mens den relativt konsentrerte tynnsyren tilføres til en avhendlngsprosess.
