Deep understanding of sustainable vanadium recovery from chrome …
The complete separation of vanadium (V) and chromium (Cr) from chrome vanadium slag is still challenging. Many studies focus on the activity of vanadium, while the effect of the other element chromium and their mutual interaction are ignored. Here, we found that proper concentration of chromium can promote the extraction efficiency of vanadium.

A sustainable and clean method for vanadium extraction from shale ore
Vanadium leaching rate of feed ore and roasted product improved from 70.48 % to 83.3 % and 9.54–12.07 %, respectively, when the acid dosage increased from 5 wt% to 10 wt%. Further increased the acid dosage to 30 wt%, the V leaching rate improved to 57.62 % and 90.85 %, respectively. It was worth noting that a sharply increase of V leaching ...
Geology of the PGE Deposits in the Bushveld Complex, South Africa
The Bushveld Complex contains 75%, 54%, and 82% of global Platinum, Palladium, and Rhodium resources respectively, as well as vast reserves of Chromium, Vanadium, Tin, Nickel, Copper, and Cobalt. The PGE resources in the BC are such that even after 100 years of mining, 6.8 billion ounces of Platinum remain.

Vanadium as a critical material: Economic geology with …
Vanadium is the 22nd most abundant element in the continental crust and it accounts for approximately 0.014% of it (Rudnick and Gao 2003); however, concentrations of at least an order of magnitude higher, and preferably two orders of magnitude higher are required for the economic recovery of vanadium from ore deposits. Global vanadium resources ...
Ore Sampling Methods: Good & Proper
With ore finely crushed, fairly dry, well mixed, and entirely free from strings and rags, and with the dividers new and exactly centering the pipe, fairly good results could be obtained by this method; but as these conditions never existed in practice, and as the edges of the cutters wore rapidly, thereby moving the dividing-line back from the ...

Sintering Characteristics of Indian Chrome Ore Fines
Chrome ore concentrate consists of high-temperature melting oxides such as Cr2O3, MgO, and Al2O3. The presence of these refractory constituents makes the ore a very high melting mineral. Hence, it is difficult to produce sinter from chrome ore by a pyrometallurgical route. Currently, chrome ore is ground to below 75 μm, pelletized, heat hardened through …
