以十二胺为捕收剂、硫化钠为活化剂，通过菱锌矿单矿物浮选试验系统研究了硫化钠用量、硫化时间、搅拌条件、加药方式以及矿浆pH值对其浮游性和硫化电位的影响。利用相关系数法分析了各因素对硫化电位的影响趋势及相关性。采用多元回归方法建立了浮选回收率与硫化电位的数学模型。利用M atlab软件拟合出硫化电位与主要因子之间的数学模型方程，结合回收率与电位的数学模型，因素与电位的数学模型为实现硫化过程的优化调控提供了理论基础。

The monomineral flotation test which for investigate the influence of the dosage of sodium sulfide and collector ,sodium sulfide treating time ,the pH of pulp ,impeller speed of flotation and the methods of adding sodium sulfide and collector on the floatability of mineral ,pulp potential and sulfide ion electrode potential have been conducted using dodecylamine as collector ,sodium sulfide as sulfide reagent . Based on multivariable regression method ,the mathematical model which reflects the relationship between flotation recovery and sulfide potential quite well was established .The influence trend of each factor on the sulfide potential and correlation between them were studied upon the correlation coefficient .Mathematical model equation between the sulfide potential and main factors was fitted out by using Matlab .The combination of mathematical models between recovery and potential ,factors and potential can provides the theoretical basis for realizing the optimizing regulation of the process of sulfidation .
