摘　　要：采用响应曲面法分析难选高硅锡中矿还原过程中相关因素对锡浸出率影响的显著性以及它们之间的相互关系。结果表明,还原时间、还原温度、配碳量对锡的浸出率影响显著且各因素之间是简单的线性关系不存在交互作用,最佳工艺条件为:还原温度850℃、还原时间1.5h、配碳量4%、矿中含硫量2.2%,在此条件下能获得98.54%的锡浸出率。Response Surface Methodology was used to analyze the factors exerting significant influence on tin leaching rate in refractory separable high silicon bearing tin middling and the relationship among them.The results show reduction temperature,reduction time and carbon content have significant influence on tin leaching rate and there is a linear relationship among factors without interaction.Tin leaching rate is98.54% under the optimum conditions including reduction temperature of 850℃,reduction time of 1.5h,carbon addition of 4%,and sulfur content in ore of 2.2%.
