【摘要】 本文绘制了25℃和100℃ Fe₃O₄—H₂O系和ZnO·Fe₂O₃—H₂O系的电位—pH图,借以从热力学上解释锌焙砂热酸浸出的试验结果,即高温（1100℃）培砂较中温（850℃）培砂易于酸分解;分析了影响铁酸钙溶解的动力学因素,并论述了湿法炼锌黄钾铁矾法和针铁矿法的加酸能力。更多还原

【Abstract】 The potential-pH diagrams for magnetite-water and zinc ferrite-water systems at 25℃ and 100℃ have been constructed, by which we can explain thermodynamically the experimental result of zinc calcine hot acid leach, i.e, high temperature (1100℃) zinc calcine is much easier to leach than ordinary zinc calcine. The kinetic factors influencing zinc ferrite acid dissolution are also analyzed. Besides, the capacities of acid addition for Goethite and Jarosite processes are interpreted.更多还原
