Scientists at PNRPU have found a simple and effective way to purify vanadium pentoxide (a product used to obtain ferrovanadium) from manganese compounds. This improves the quality of vanadium-containing steel, according to the university's press service.
Vanadium pentoxide is usually washed with reagents, using solutions of sodium, magnesium, calcium, ammonium, aluminum, and iron salts. Permian scientists compared the results of using these reagents. The study was commissioned by the Chusovoy Metallurgical Plant.
We found that the best results for purification from manganese compounds are achieved using ammonium sulfate, ammonium nitrate, and calcium nitrate.
At the same time, the content of manganese compounds in vanadium pentoxide decreases by more than 4 times. The use of other salt solutions proved ineffective.
