Abstract

This study was carried out magnetic separation experiments for vanadium recovery and mineralogical characterization on domestic Vanadium Titanomagnetite (VTM). Additionally, a beneficiation process was developed to recover not only vanadium but also titanium. The head ore used in this study was 0.54% based on V₂O₅, and it was analyzed that more than 80% of magnetite and ilmenite were contained. As a result of the magnetic separation, it was found that the magnetic intensity of 0.05T is effective in improving the grade of vanadium and 0.1T is effective in improving the recovery. Based on this, a magnetic separation process was developed to recover concentrates with a grade of 1% and a recovery of 82.39% based on V₂O₅. Also, based on the previous experimental results, the development of a process capable of recovering titanium as well as vanadium was developed to simultaneously recover vanadium concentrates with V₂O₅ grade of 1.06% and 88.41% recovery, and titanium concentrates with TiO₂ grade of 42.20% and 73.39% recovery.

본 연구에서는 국내 바나듐 티탄철광(Vanadium Titanomagnetite, VTM)으로 대상으로 광물학적 특성분석 및 바나듐 회수를 위한 자력선별 실험을 실시하였다. 또한 바나듐뿐만 아니라 티타늄도 함께 회수하기 위한 선별 공정개발을 수행하였다. 본 연구에 사용된 원광의 품위는 V₂O₅ 기준으로 0.54%이며, 자철석 및 티탄철석이 80%이상 함유되어 있는 것으로 분석되었다. 자력선별 실험 결과, 자력의 세기 0.05T는 품위 향상에 0.1T는 회수율 향상에 효과적인 것을 알 수 있었다. 이를 바탕으로 자력선별공정도를 개발하여 V₂O₅ 기준으로 품위 1%, 회수율 82.39%인 정광을 회수하였다. 또한 앞선 실험결과를 바탕으로 바나듐과 함께 티타늄도 회수 가능한 선광 공정 개발을 진행하여, 품위 1.06V₂O₅%, 회수율 88.41%인 바나듐 정광과 품위 42.20TiO₂%, 회수율 73.39%인 티타늄 정광을 동시에 회수할 수 있는 공정을 개발하였다.
