| titleOfInvention | Method of processing vanadium containing converter slag |
| abstract | FIELD: metallurgy. n SUBSTANCE: method consists in crumbling, in oxidising annealing converter slag with production of ash, in leaching vanadium from ash with solutions of alkali and in extracting vanadium salts from vanadium solution. Converter slag containing reverse manganese additives over 20 % MnO, preferably 25-27 %, at ratio of manganese to vanadium equal to 1.5-1.7 is annealed during 1.0-1.5 hours at temperature 800-850°C, further vanadium is selectively leached from ash with solution of alkali at presence of carbon dioxide gas at mole ratio CO 2 : Na=0.5-1 or vanadium and manganese are collectively leached at pH 1.5-2.5 with sulphuric acid or spent electrolyte after production of electrolytic manganese dioxide and are extracted from solution of vanadium and manganese salts. n EFFECT: reduced number of operations for preparing slag, reduced losses of vanadium with metal sifting, increased efficiency of annealing furnace; and reduced scull formation. n 1 dwg, 2 ex |
