为了降低钒钛磁铁矿的还原和熔分温度，提高钛与钒的回收率，采取碳热钠化还原法处理钒钛磁铁矿，研究了钠化剂对钒钛磁铁矿还原以及熔分后钛、钒分布的影响。结果表明，钠化剂能显著改善钒钛磁铁矿的还原性以及磁选和熔分效果，钠化比为1.2时，1 100 ℃还原60 min即可达到90%以上的金属化率，磁选后铁的收得率达到92%以上，铁品位接近80%。1 450 ℃以上的温度熔分后，铁的收得率高于95%，钒在铁水中的分配比为91%，熔分渣水洗后[w(TiO2)]达到56%。

In order to reduce the reduction and smelting-separation temperatures of vanadium-bearing titanomagnetite， and improve the recovery rate of Ti and V， the carbothermic reduction in combination with sodium-treatment was studied， and the effects of sodium agent on reduction as well as the distribution of Ti and V after smelting-separation were discussed. The sodium agent significantly improves the reducibility， the magnetic separation as well as the smelting-separation performance of vanadium-bearing titanomagnetite， the metallization ratio reached 90% at 1 100 ℃ for 60 min when the sodium ratio was 1.2， and the fine iron concentrate with a iron grade of 80% as well as iron yield of 92% was obtained after magnetic separation. The iron yield was higher than 95%， and the distribution ratio of V reached 91% when the sample was smelting-separated at 1 450 ℃. Moreover，[w(TiO2)]in slag reached 56% when the smelting-separation slag was washed in water.
