METHOD OF PROCESSING VANADIUM-CONTAINING CONVERTER SLAG Russian patent published in 1995 - IPC

Abstract SU 1702705 A1

FIELD: ferrous metallurgy. SUBSTANCE: method involves oxidative-sodium roasting slag with soda, aqueous leaching cinder at mechanical stirring, isolation of vanadium compounds from solutions. Cinder leaching at mechanical stirring is carried out up to attainment of vanadium concentration in solution ≥ 24 g/l V2O5 followed by simultaneous action of mechanical stirring and vibration of apparatus bottom. Leaching degree is 98.3% (in prototype 95%). EFFECT: increased vanadium extraction degree from slag. 1 dwg, 3 tbl
