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.
