The ores of ti, ta and nb may be brought into solution near 800°c using na2s207. a simplified reaction may be as follows: tio + nazs;0> na,sos +tio(so) the acid

The ores of Ti, Ta and Nb may be brought into solution near 800°C using Na2S207. A simplified reaction may be as follows: TiO + NazS;0> Na,SOs +TiO(SO) The acid and base in the reaction are: (a) Ti as base and Na in NazS20 as acid C)Oof TiO, (base) and SO; in S.0, (acid) 17. (b) S2S7 as base and 02 as acid (d) Ti as acid S* as acid.
