Thus, metallic Fe is difficult to be separated from reduced vanadium slag by magnetic separation. SEM and EDS of reduced vanadium slag at 1200 °C were shown in Fig. 5 (b) and (c). The size of metallic Fe particles increased with increasing temperature to 1200 °C, which can be attributed to promote migration of metallic Fe phases.

Vanadium - Wikipedia

Vanadium is a chemical element with the symbol V and atomic number 23. It is a hard, silvery-grey, malleable transition metal.The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer (passivation) somewhat stabilizes the free metal against further oxidation.
