V-containing magnetite can occur as either the titanoferrous material or Ti-free magnetite. V-containing titanoferrous magnetite generally has low Ti and Fe contents, and enrichment to produce V-containing iron concentrate is performed to meet the requirements of ironmaking in blast furnaces.
To use vanadium–titanium magnetite (VTM) resources for sintering, a composite agglomeration process (CAP) is applied. This paper studies the effects of pelletizing parameters, including particle size, moisture content and bentonite content on VTM green pellets, composite agglomeration process and mineralogy.
Vanadium-containing titanomagnetites are processed in two ways for the production of steel and vanadium products (sequences): hot metal—vanadium slag—steel. soda roasting—lixiviating—vanadium pentoxide. China has a rich reserve of vanadium-containing titanomagnetites, which is distributed over a vast area.
In this experiment, vanadium-titanium magnetite (VTM) is treated by the composite agglomeration process to prepare blast furnace burden and the resulting sinter performance is compared with conventional sintering process.

Abstract At present, the methods of comprehensive utilization of vanadium-titanium magnetite tailings are mainly divided into two categories: tailings reseparation (Valuable metal recycling) and overall utilization.
The influences of various factors, such as oxygen enrichment time, oxygen enrichment load, and ignition temperature, on the technical indices and sintering performance in the vanadium-titanium magnetite sintering process are simulated using sinter pot experiments.
As an important mineral resource, Vanadium titanium magnetite (VTM) has a high comprehensive utilization value due to it containing abundant high-value elements such as vanadium and titanium [ 1 ]. It is usually used as the iron-containing raw material for sintering process.
Many technologies exist for the treatment of titaniferous magnetites that contain vanadium. Each process is designed based on the relative amounts of titanium, vanadium and iron. In some cases, steelmaking is the primary purpose followed by the secondary recovery of vanadium. In others, the vanadium is the main product. This …

According to the nature and composition of the tailings, in the tailings reseparation uses gravity separation, magnetic separation, …
The main phase composition of VTM is titanomagnetite and ilmenite. When the amount of bentonite is 1%, the compressive strength and dropping strength of VTM pellets can meet the requirements. To improve metallurgical properties, the pellets need to …
Titanium-bearing magnetite ore is generically defined as magnetite with > 1% titanium dioxide (TiO2) and is usually vanadium-bearing. The iron and titanium occur as a mixture of magnetite (Fe3O4) and ilmenite (FeTiO3) with vanadium oxide usually occurring within the solid solution of the titanium-bearing magnetite phase. These ores …

In general, the direct vanadium extraction process is applied by sodium salt roasting and water leaching [10,11] or calcium salt roasting and acid leaching [12]. The vanadium was dissolved in the leachate, then the operations of purification, enrichment, precipitation and calcination were applied to obtain the product of V2O5[1,13].

vanadium–titanium magnetite is another major raw material from which to extract vanadium. China's vanadium–titanium magnetite reserves are huge—up to 9.83 billion tons that reach mineable grade—and are therefore of high utilization value [2,3]. Generally, the indirect vanadium extraction process takes place after iron-making; vanadium
