2015-11-25 accounts for 40% of the total ore [10]. Most of the mined stone coals are of low grade and require beneficiation to obtain vanadium concentrate. If vanadium beneficiation is successful, a reasonable amount of production cost will be reduced. ZHAO et al [8] attempted to pre-concentrate vanadium value from stone coal by

2014-5-6 pre-concentrate vanadium from stone coal. Even though only 9.7% vanadium was lost by this method, the yield of tailing was low and only accounted for 28.9% of the feed ore. Among various kinds of beneficiation methods, flotation has been widely used in the treatment of sulfide and oxide ores due to its high throughput and selectivity [13,14]. In stone coal, vanadium mainly exists in illite,

2018-8-15 Form the above given results, it can be seen evidently that the conventional methods of beneficiation are ineffective to obtain high-grade concentrate from the stone coal ore. Secondly, vanadium cannot be leached directly, since the trivalent vanadium, V 3+, embedded in the crystal lattice of mica minerals is insoluble in acid and water.
