Meeting 2017 TMS Annual Meeting & Exhibition
Symposium 8th International Symposium on High Temperature Metallurgical Processing
Presentation Title E-12: Study on Vanadium-titanium Gas-based Direct Reduction-grinding and Separation Process
Author(s) Jingkun Tang
On-Site Speaker (Planned) Jingkun Tang
Abstract Scope A gas-based direct reduction technology was adopted for comprehensive utilization of Vanadium-Titanium from Mozambique, and the influence of processing parameters on the reduction effect, such as additive agent NCP dosage, reduction temperature, and reduction time, was studied. The results show that, after a reduction under the conditions such as the NCP dosage of 2%, the reduction temperature of 950℃ and the reduction time 240min, the metal ratio of oxide pellets reached 93.68%. Meanwhile, the influence of processing parameters on the grinding magnetic separation effect, such as grinding time, the intensity of magnetic separation, also was researched. Metal pellets which were grinded and beneficiated with a low intensity magnetic separator, and the TFe grade and recovery for the iron concentrate powder reached 79.25% and 91.12%, respectively, the V2O5 and TiO2 grade of slag reached 1.9% and 30.46%.
