Ag. Artemenko et Dl. Motov, KINETICS OF THE SPHENE CONCENTRATE REACTION WITH 65-70-PERCENT SULFURIC-ACID LEADING TO TITANIUM(IV) DISSOLUTION, Russian journal of applied chemistry, 69(3), 1996, pp. 330-334
The kinetics of the sphene concentrate sulfation at 100, 130, 140, and
150 degrees C with titanium(IV) transfer into solution was studied wi
th the aim to elucidate the mechanism of this process.
