Extractive metallurgy of vanadium-containing titaniferous

The main methods of extracting vanadium from vanadium-titanium magnetite are direct extraction and indirect extraction. Vanadium can be recovered either before or after the iron-smelting processThe Huanggangliang deposit is a super-large Sn-Fe deposit in the Huanggangliang–Ganzhuermiao metallogenic belt in the southern section of the Great Hinggan Range.

Extractive metallurgy of vanadium-containing titaniferous magnetite

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 paper
