摘要： 实验测定了不同温度Mn-Fe-C熔体中C的溶解度，目的在于获得Mn-Fe-C熔体活度相互作用系数，用新的方法处理实验数据. 通过热力学推导和计算，获得了Mn-Fe-C熔体某些重要热力学性质与温度(1350℃?T-273?1450℃)的关系式.

关键词: Mn-Fe-C熔体, 活度相互作用系数, 热力学性质, 线性回归, 温度

Abstract: Bioleaching of Nicopyrite was studied and the following conclusions were drawn from the experiments: (1) The bacteria attached on the surface of the minerals had the most important contribution to the dissolution of Nicopyrite, the free bacteria in the solution had minor contribution; (2) Fe2+ was mainly oxidized by free bacteria in the solution; (3) The incomplete oxidation of S can lead to rising of pH value in solution.

Key words: Mn-Fe-C melt, activity interaction coefficient, thermodynamical properties, linear regression, temperature
