Extraction of Vanadium From Stone Coal by High-temperature Leaching With Water
摘要
Abstract
To solve the problem of vanadium in stone coal to transform insoluble vanadium bronze because of secondary reactions during calcine cools slowly ,a new technology for leaching vanadium by leaching the high-heat calcine directly with water was proposed .The influences of the main factors including temperature ,leaching time and liquid-solid ratio were examined through singular factor experiments and orthogonal experiments .The optimal leaching conditions determined was temperature of 650 ℃ ,leaching time of 9 h and liquid-solid ratio of 2 mL/1 g .T he leaching rate of vanadium reach up 89% under the optimal conditions .T his method could improve leaching rate of vanadium by reducing the generation of insoluble vanadium bronze and speed up the leaching process by effectively utilize the heat from the high-heat calcine .关键词
