| Abstract: | After comparing the results of vanadium extraction by roasting the mixture of calcium-bearing regents with vanadium titanomagnetite concentrate and leaching by deionized water and roasting the mixture of sodium-bearing regents with iron concentrate and leaching by acid,the extraction method of vanadium by roasting the mixture of calcium-bearing reagents with iron concentrate and leaching by sulfuric acid is proposed.Among roasting additives of Na2CO3,CaO,Ca(OH)2 and CaCO3,CaCO3 has the best effect for vanad... |
| Keywords: | vanadium titanomagnetite calcination with calcium compound acid leaching extraction of vanadium |
