摘要： 针对攀枝花钒钛磁铁矿进行了金属化还原-选分-电热炉熔分实验，考察了磁场强度、还原温度、还原时间、配碳比、还原煤粒度对金属化还原及磁选分离效果的影响.实验结果表明，当磁场强度50mT、还原温度1350℃、还原时间60min、配碳比10、还原煤粒度为-75μm时，金属化还原后产物及磁选分离磁性物质、非磁性物质的各项指标最佳，进一步进行电热炉熔分可实现铁钒分离.新工艺达到铁钒钛资源高效分离要求，铁钒钛收得率分别为9507%，7160%和8008%.

Abstract: Metallization reduction—magnetic concentration—electroheat melting separation experiments on vanadium titanomagnetite from Panxi region in Sichuan province were conducted， and the effects of the factors such as magnetic density， reduction temperature， reduction time， carbon ratio and coal particle size on the metalized reduction and magnetic separation were investigated. The results indicated that optimal conditions for the metallized reduction—magnetic concentration—electroheat melting separation are as follow:the magnetic density 50mT， the reduction temperature 1350℃， the reduction time 60min， the carbon ratio 10 and the coal particle size -75μm. Based on the new process， the effective separation of iron， vanadium and titanium can be realized. The yield of the iron， vanadium and titanium is 9507%， 716% and 8008% respectively.

Key words: vanadium titanomagnetite, metallization reduction, magnetic concentration, electroheat melting separation, technique specifications
