摘要
本文从热力学角度研究了ＦｅＣｌ３－ＨＣｌ－ＮａＣｌ体系从辉银矿（Ａｇ２Ｓ）中浸取银的原理，分析了ｐＨ值、Ｆｅ３＋与Ｃｌ－浓度以及反应温度等浸取热力学条件对反应的影响，并由阿仑尼乌斯公式推导出反应活化能。
Based on the thermodynamic theory,the leaching principle of Ag from argentite (Ag 2S) in FeCl 3 HCl NaCl system is studied in this paper.The effect of leaching thermodynamic conditions such as pH,concentration of Fe 3+ and Cl -,and temperature on reaction is analysed.The reaction activation energy is derived with Arrhenius formula.
