Ferrovanadium smelting method - thermite method. Aluminum is used as the reducing agent, and the bottom ignition method is used for smelting in a furnace barrel lined with an alkaline furnace. First put a small part of the mixed charge into the reactor and ignite it. After the reaction starts, add the rest of the charge one after another. It is usually used to smelt high vanadium iron (containing 60~80% vanadium). The recovery rate is slightly lower than that of electrosilicothermal method, about 90~95%.
Commonly used ferrovanadium contains 40%, 60% and 80% vanadium. The main raw material for China's ferrovanadium production is vanadium-titanium magnetite. After beneficiation and enrichment, vanadium-containing pig iron is smelted through a blast furnace, and vanadium slag is extracted during the atomizing furnace or converter blowing process.
After the vanadium slag is crushed, sodium salt (soda ash, table salt or anhydrous Glauber's salt) is added for sodium oxidation roasting to turn the vanadium into soluble sodium metavanadate (NaVO3). After leaching and purification, ammonium sulfate is added to precipitate polyvanadate.
Ammonium [(NH4)2V6O16] is then melted by deamination and cast into flake-shaped vanadium pentoxide. The required ingredients are V2O597~99%, P<0.05%, S<0.05%, Na2O+K2O<1.5%. In addition, vanadium pentoxide is also extracted directly from vanadium-containing iron concentrate or vanadium-containing carbonaceous shale through chemical treatment.
