摘　　要：研究以铝土矿尾矿、浓硫酸为原料,使用浓硫酸酸解工艺,对氧化铝浸取模型的建立进行了实验研究。实验结果表明影响氧化铝浸取率的影响因子为反应温度、反应时间、液固比以及尾矿颗粒粒度,使用软件拟合出4个影响因素对氧化铝浸取率的回归方程,确定各因素相关系数,建立浸取过程的数学模型。检验结果表明,该数学模型的实验误差在5%以内,具有一定的可信度。Basing on bauxite tailings and concentrated sulfuric acid as raw materials, Model on leaching alumina from bauxite tailings was studied started with craft parameters with concentrated sulfuric acid leaching process. Results of experiment show that four craft parameters such as reaction temperature, reaction time, liquid-solid ratio and particle size of tailings can influence alumina leaching rate. Regression equations on alumina leaching rate were established through software. The correlation coefficients were obtained and the model was established. Results indicate that the error rate of this model is less than 5 %, and the model is reliable.
