摘　　要：采用相应曲面法,建立钙化添加剂用量、焙烧温度、焙烧时间与钒浸出率关系的数学模型,对钒渣微波钙化焙烧提钒工艺进行优化,并对试验结果的可靠性进行分析与验证。研究结果表明,采用响应曲面法优化钒渣微波钙化焙烧提钒工艺参数是可行的;微波钙化焙烧工艺参数对钒浸出率的影响从大到小依次为钙化添加剂用量、焙烧温度、焙烧时间;最佳焙烧参数为焙烧温度861.69℃、钙化添加剂用量1.02、焙烧时间106.31 min,此时钒的浸出率可达93.82%。The mathematical model of the relationship between calcification additive dosage, roasting temperature, roasting time and vanadium leaching rate was established by response surface method. The vanadium extraction process by microwave calcification roasting of vanadium slag was optimized, and the reliability of the test results was analyzed and verified. The research results show that it is feasible to optimize the microwave calcification roasting process for extracting vanadium from vanadium slag by response surface methodology. The influence of microwave calcification roasting process parameters on vanadium leaching rate in descending order is calcification additive dosage,roasting temperature, and roasting time. The optimum roasting parameters are as follows: the roasting temperature is 861.69 ℃, the dosage of calcification additive is 1.02 and the roasting time is 106.31 min.at this time, the leaching rate of vanadium can reach 93.82%.
