A new method of deep-reduction and high pressure acid leaching was introduced to prepare rich titanium material with the pre-oxidized titanium slag from Yunnan as raw material,and the effects of atmosphere,temperature,time and cooling system on the reduction were discussed. The results show that with 700 L/h of air flow rate,1 000 ℃ of temperature for 2.5h and 5 ℃/h of cooling rate for the reduction of pre-oxidized titanium slag,a relatively higher reduction rate of iron oxides can be obtained and the slag phase is partially damaged,with significantly high leaching rate of impurities satisfying requirements of rich titanium material for titanium dioxide production by chlorination process.
