Vanadium was recycled through the extraction process using 2-Ethylhexyl diphenyl phosphate (D2EHPA), while Manganese was recovered via precipitation with Na 2 CO 3 (Table 9 is shown the optimal conditions and recovery efficiency). Besides precipitation for the extraction of manganese from wastewater, electrolysis also hold significance.

The vanadium content accounts for about 0.02 % of the earth's crust, which is larger than copper, tin, zinc and nickel, but it belongs to rare metals because of the scattered distribution in the crust [1].In nature, vanadium distribution is relatively scattered, mainly symbiotic with other minerals, crude oil, coal, etc. [2], [3], [4].The main raw materials for vanadium extraction are …
