摘　　要：本文研究了温度、矿石试样粒度和搅拌速度等因素对钙芒硝矿中硫酸钙溶解速度的影响。由实验数据求得钙芒硝矿中硫酸钙溶解过程的表现活化能为50.54kJ/mol。所得结果为确定钙芒硝矿的溶解条件和开发阻溶硫酸钙的技术提供了依据。In this paper,the conditions which affect the dissolution rate of calcium sulfate in glauberite ore such as temperature,grain—size of the ore,stirring rate,time of dissolution and so on have been studied.According to the expertmental data the apparent activation en- ergy for the dissolution of calcium sulfate in gluberite is 50.54kJ/mol.The conclusions given in this paper can be utilized to determine the optimum conditions of dissolution and develop the technique for inhibiting the dissolution of calcium sulfate.
