摘　　要：用多相多组元化学平衡的热力学理论模型对氯化焙烧过程进行了预测,找出影响镓的提取率的关键因素,利用通用旋转组合设计的方法得出了镓的提取率与温度、CaCl_2的加入量、C的加入量、焙烧时间及气氛的非线性模型。由非线性优化得到了最优的工艺条件及镓的最佳提取率。Ga extraction from vanadium-leaching slag by chloridizing roasting is simulated using SMT; with combination of the traditional orthogonal design, regression analysis and nonlinear program,a new optimization experiment design has been made to obtain the optimum technological conditions with the minimum number of experiments. The nonlinear model of Ga extraction,the optimum result of Ga extraction rate and the optimum conditions have also been obtained.
