Engineering an integrated process for efficient Fe–V–Ti separation and utilisation from vanadium–titanium magnetite
Vanadium–titanium magnetite (VTM) is a typical complex multi-metal iron ore that contains significant amounts of iron, vanadium, and titanium. Owing to the strong mineralogical coupling among these elements, efficient separation and comprehensive utilisation of VTM remain major technical challenges in ironmaking and extractive metallurgy. Conventional blast furnace and direct reduction routes primarily focus on iron production, often leading to inefficient vanadium recovery and limited utilisation of titanium, which is usually concentrated in slag with low added value. With the increasing demand for vanadium in high-strength steels and energy storage applications, as well as the growing importance of titanium resources, the development of an integrated and industrially feasible process for the coordinated recovery of Fe, V, and Ti from VTM has become increasingly important. In this study, an integrated metallurgical route combining sodium salt roasting, hydrometallurgical vanadium recovery, pellet conditioning, coal-based pre-reduction, and electric furnace smelting separation was developed and systematically investigated. The proposed process aims to achieve high-efficiency vanadium extraction while maintaining favourable physical and metallurgical properties of the solid residue for downstream high-temperature treatment. Particular emphasis was placed on addressing key engineering challenges associated with residual alkali, Ti rich phases, and pellet integrity, which often limit the applicability of sodium salt roasting–leaching routes in industrial practice.
