摘要
该研究是为了开发钒钛磁铁矿(VTM)的还原预处理钒回收工艺而进行的。该研究的样品由京畿道抱川的冠仁矿提供。样品中钒含量为0.54 v2o %，钒主要富集在磁铁矿和钛铁矿中。磁选后样品的钒含量可提高1.10 V / 2o %。为了进一步提高钒含量，进行了还原预处理，即利用碳(C)还原磁铁矿中的铁，将铁中的钒富集。在此还原预处理的基础上，开发了磁选工艺，钒品位为1.31 v2o %，回收率为79.68%。并对还原前后钒精矿及最终钒精矿进行XRD分析，确定了还原预处理后钒的行为。
Development of Vanadium Recovery Process Using Reduction Pre-treatment from Vanadium Titanium-Magnetite (VTM) Ore
The study was conducted to develop a vanadium recovery process using reduction pre-treatment in the Vanadium TitanoMagnetite (VTM) The sample for the research was provided by the Gwan-in Mine in Pocheon, Gyeonggi-do. The vanadium content of the sample is 0.54 V 2 O 5 % and vanadium is concentrated mainly in magnetite and ilmenite. Magnetic separation of the sample can increase vanadium content up to 1.10 V 2 O 5 %. To increase the vanadium content further, reduction pre-treatment was performed, which is a process of concentrating vanadium present in the iron by reducing iron in magnetite using carbon(C). Based on this reduction pre-treatment, the magnetic separation process was developed, which achieved a vanadium grade of 1.31V 2 O 5 % and 79.68% recovery. In addition, XRD analysis of the vanadium concentrate before and after reduction and the final vanadium concentrate was performed to confirm the behavior of vanadium by reduction pre-treatment.
