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.

However, attention is usually paid to niobium ...



A thorteveitite ore beneficiation process which comprises comminuting the ore by wet autogenuous grinding to substantially liberate the thortveitite contained therein, and passing the comminuted ore through a nonuniform magnetic field to produce a concentrate and a tailing, the concentrate containing a substantially greater percentage of thortveitite than the ore.





With chloride waste, potassium, magnesium, niobium, tantalum, scandium, manganese, chromium and other valuable metals are lost. In the waste of titanomagnesium production there are also rubidium and cesium, the distribution of which by industrial products and wastes is not sufficiently studied. ...

REE generally occur in ore deposits with other elements and compounds as trivalent cations in mineral phases such as carbonates, oxides, halides, phosphates, and silicates. Froth flotation and physical separation techniques such as magnetic, multi-gravity and electrostatic separation have been exploited in the beneficiation of REE minerals.



Elevate Uranium (ASX: EL8) has received binding commitments for a $25 million two-tranche placement to accelerate the next phase of development at the Koppies uranium project in Namibia. Tranche 1 will see the company issue approximately 32.4 million shares priced at $0.325 each, while Tranche 2 will issue a further 44.5 million shares at the same price.

The rare earth elements (REEs) are considered to be scandium, yttrium and the elements of lanthanide group, which are included together due to their chemical similarity (Krishnamurthy and Gupta, 2016).Among those, scandium is the most valuable (Table 1).Its application in modern advanced technologies are found in light-weight aluminium alloys, where …



Discovery of scandium in the Vitro solvent extraction plant for uranium led to commercial recovery of the byproduct. Micro amounts of scandium were extracted with uranium by dodecyl phosphoric acid, but failed to follow ura-niuminto the hydrochloric acid strip solution and were eventually concentrated in the organic extractant. A fluoride strip system was developed to …



3.2 Efficacy of Reduction Pre-treatment on the Extraction of Nickel, Cobalt and Scandium from Laterite Ore. Efficacy of reduction pre-treatment of laterite ore on the extraction of Ni, Co, and Sc was determined by comparing the %recovery obtained between leaching untreated ore and reduced ore (treated at 700 °C for 40 minutes) ...





During the scandium oxide production, the beneficiation stage contributes around 88% of the overall impact (Fig. 3 a). The main processes affecting the potential environmental impact in the beneficiation stage are Fe separation (II) (30%), and Fe separation (III) (20%), both of which account for more than half of the total impact.



This study investigated the leaching of scandium from a Sc-bearing silicate ore. The Sc concentrate obtained by beneficiation pre-enrichment has 1.03 × 10 ‑4 wt% Sc and 14.66 wt% Fe.
