摘　　要：现行钒渣焙烧工艺中的钒渣高温物理热被浪费,对"熔融钒渣直接氧化钠化提钒"新工艺的可行性进行分析,并进行实验室模拟试验。结果表明,新工艺条件下,试验过程中熔融钒渣流动性良好,焙烧后钒渣水浸率为50%～80%,焙烧后钒渣中的钒主要以偏钒酸钠的形式存在。新工艺是合理可行的,具有工业生产价值。A new process of extracting vanadium from molten vanadium slag by direct oxidation and sodium salt roasting method was introduced,with the aim to address heat waste of vanadium slag existing in vanadium extraction process through vanadium slag roasting.The feasibility of the new process was analyzed,and the simulation test was carried out in laboratory.The results show that under the new process condition,molten vanadium slag can be kept with good fluidity.Water leaching rate of vanadium is 50%～80%.Vanadium in roasted slag exists in form of sodium metavanadate.To conclude,the new process is feasible and can meet industrial production requirement.
