摘　　要：本文阐述了硫酸直接浸取含钒灰渣提钒工艺中,硫酸浸取,浸出液中提取铵明矾、再提取中间盐并溶解之,溶剂萃取、反萃及沉钒的有关因素。并确定了最佳工艺条件。The effecting factors on the process of the abstraction of vanadium from vanadiferours cinder by sulphurie acid direct leaching are discussed. The discussion includes the abstractinof ammonia-alum from leached liquid, the abstraction of intermediate salt and its soluation, solvent extraction, stripping and the precipitation of vanadium. The optimal condition of the process is hence defined.
