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 0.05 T is effective in improving the grade of vanadium and 0.1 T 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.

Tin is widely used as a material for soldering and plating because it is non-toxic and highly corrosion resistant and has a low melting point. Recently, the demand for tin has increased rapidly with the development of the electric and electronic industries, along with the expansion of its use as a raw material for next-generation secondary batteries. Cassiterite is the main ore mineral of tin, and more than 65% of the world's cassiterite reserves are situated in China, Indonesia, Myanmar, and Australia. In addition, some partial reserves are located in Uljin and Sangdong in Korea. Currently, research conducted in Korea has focused on securing tin resources to avoid dependency on imports. Technological development is required to secure stable tin supplies in the future.
