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
