摘　　要：随着钛需求的不断扩大,研究钛精矿的高效开发利用具有重要意义,特别是以氢为还原剂的绿色火法冶炼生产高钛渣工艺研究备受关注。采用管式炉氢还原钛精矿,试验结果表明,钛精矿在反应温度1 000℃,反应物粒度小于0.088 mm,反应时间20 min以上的条件下,还原效果较好。With the increase of titanium demand,the research on the reasonable utilizaion of titanium concentrate shows an important meaning,especially the environmental friendly pyrometallurgical process for high titanium slag preparation becomes a hot spot.The reduction processes of titanium concentrate with hydrogen gas in the tubular-furnace are discussed.It indicates that it has better reaction effect for titanium concentrate under the temperature of 1 000 ℃,with particle size of-0.088 mm and reaction time up to 20 min.
