In order to explore the effect of air humidification on sintering performance of vanadium-titanium magnetite concentrate,sinter layer surface air humidification test had been carried out in the laboratory. From the experimental results it is found out thatspraying 0.4% water after 18 minutes of the ignition,generated the maximum yield where utilization coefficient is 1.31 t/(m2·h) and yield increases by 15.94% compared with the benchmark; At the same time the second best yield has been achieved when secondary ignition sintering is completed without water spray,consequently utilization coefficient is 1.281 t/(m2·h) and yield increases by 13.40%. On the other hand,when a composite index is used for evaluation,the best result comes from the 0.4% water spray after 18 minutes ignition with composite index of 98.54,followed by implementation of second ignition sintering (not spray) with composite index of 98.50,and the worst case is 0.3% water spray after 18 minutes ignition with its composite index of 97.33.Nevertheless,all three processes can produce higher composite index than the baseline of 96.25.
