  • Owing to the global development of high-strength alloys and renewable energy industries, the demand for vanadium, a key raw material in these industries, is expected to increase. Until now, vanadium has been recovered as a by-product of the industry, but interest in its direct recovery from minerals has increasing with its significantly increasing demand. In particular, the recovery of vanadium from stone coal ore and vanadium titano-magnetite (VTM) containing vanadium has been actively researched in China, which has the largest reserves and production of vanadium in the world. In Korea, a large amount of VTM also occurs in the northern part of Gyeonggi-do, and fundamental research and technical development is being conducted to recover vanadium. It is necessary to understand the current status of the separation technology used worldwide to satisfy the demand for metals such as vanadium, which currently depends on imports.

  • Optimized recovery of heavy minerals from the near shore sands of Korean Yellow Sea was investigated using physical processing technologies such as gravity concentration and magnetic separation. The head samples were subjected to the three stages effective separation; Head sample was first treated by a spiral separator to recover rough heavy mineral concentrates, which are contained minerals like ilmenite, zircon and rare earth minerals. Much higher beneficiation processes were subsequently taken by wilfley table and magnetic separation according to their magnetic field responses. Heavy minerals were effectively recovered by wilfley table and subsequent recleaning of heavy minerals by magnetic separations was conducted. Qualitative and relative-quantitative analyses of their constituent elements were doing using XRD and XRF.
