Vanadium exists in multiple oxidation states in natural systems. Combinations of V(iii), V(iv), and V(v) may be present in over 300 minerals, forming at least nine ionic complexes in water at 25 °C depending on the redox and pH conditions (Pourbaix, 1975, Gao et al., 2021).This chemical versatility has led to a wide range of possible extraction methods for vanadium ores.
In this work, we investigated the mechanism of enhanced vanadium extraction from shale ore by suspension oxidation roasting (SOR) by comparing the leaching behavior between traditional …
The chemistry of vanadium extraction from vanadium-rich slag by the salt roast/water leach process is quite similar to that involved when processing ores and concentrates, although the optimum conditions and reagent dosages will differ from those for the processing of ores/concentrates.
Today, approximately 88% of vanadium is produced from vanadiferous titanomagnetite ores (Rappleye and Haun 2021) including iron- and steel-slags, which represent more than 69% of the starting raw material in …

Vanadium-bearing shale is widely distributed in many provinces of China with a low vanadium grade (usually less than 1%) [5].However, the ores which from the different regions are very different in element content, mineral composition, occurrences of vanadium, and mineral association relationship because of long-term weathering, leaching, and alteration.
The most renowned downstream processing of the acidic leachates derived from processing of colombo-tantalite ores is based on solvent extraction (SX). This process achieves efficient separation of Ta and Nb from the leachates while eliminating the unwanted accompanying impurities.
Vanadium occurrences in laterite, bauxite, and phosphate ores: vanadium can be associated with bauxites, laterites and supergene iron ores (Gamaletsos et al., 2017).
