研究了用氯化铵溶液浸出氧化锌矿过程中反应条件对锌浸出率的影响。结果表明,在搅拌速度300r/min,矿样平均粒径0.075mm,反应温度90℃,氯化铵浓度5mol/L,反应时间4h条件下,锌的浸出率近90%,浸出液中铁质量浓度仅为0.61mg/L。
The Effects of some reaction conditions on leaching of zinc from zinc oxide ore with ammonium chloride solution are investigated. The results shows that leaching of zinc is about 90% under the optimum conditions which stirring rate is 300 r/min, average particle size of ore is 75 μm, temperature is above 90℃, ammonium chloride concentration is 5 mol/L and reaction time is 4 h. The iron concentration in leaching solution is 0.61 mg/L.
