Abstract：The influence of the ratios of limonite on the basic characteristics of vanadium titanium magnetite was investigated．The results show that the assimilation temperature of vanadium titanium mixed ore decreases with the increasing of the ratio of limonite．The liquid phase fluidity index of vanadium titanium mixed ores rises with the increasing of the ratio of limonite．The binding phase strength of vanadium titanium mixed ores rises at first and then decreases with the increasing of the ratio of limonite．The assimilation temperature of vanadium titanium mixed ores is 1302~1315℃，the liquid phase fluidity index is 1.12~1.32 and the binding phase strength is 4628~5198N in different ratios of limonite．Based on comprehensive utilization of low-priced materials，decrease the cost of production and improve the quality of vanadium-titanium sinter，analyzed the influence of the ratio of limonite on the basic characteristics of vanadium titanium magnetite，the sintering ore-blending scheme is best when the ratio of limonite is 10% and the total ratio of limonite is 37.2%．
