改性对高钛渣酸解性能的影响研究

Abstract

Abstract: With Na2CO3 as the modifier，the effect of modifier content，roasting temperature，and roasting time on the acidolysis performance of high-titanium slag had been investigated.Research results showed that the better experimental conditions of modification were that the temperature was 850 ℃，the mass ratio of Na2CO3 to high-titanium slag was 0.7，and the roasting time was 3 h.The modified high-titanium slag was used in the acidolysis.Under the conditions of dissolving temperature of 60 ℃，dissolving time of 4 h and mass ratio of solid to liquid of 1∶6，the dissolving rate of Ti reached 97.48%.

Key words: hydrochloric acid method, high-titanium slag, modifier, roasting process
